Convert `OldDiagnostic::noqa_code` to an `Option<String>` (#18946)
## Summary

I think this should be the last step before combining `OldDiagnostic`
and `ruff_db::Diagnostic`. We can't store a `NoqaCode` on
`ruff_db::Diagnostic`, so I converted the `noqa_code` field to an
`Option<String>` and then propagated this change to all of the callers.

I tried to use `&str` everywhere it was possible, so I think the
remaining `to_string` calls are necessary. I spent some time trying to
convert _everything_ to `&str` but ran into lifetime issues, especially
in the `FixTable`. Maybe we can take another look at that if it causes a
performance regression, but hopefully these paths aren't too hot. We
also avoid some `to_string` calls, so it might even out a bit too.

[`FastAPI`] Add fix safety section to `FAST002` (#18940)
## Summary

Part of #15584

This PR adds a fix safety section to [fast-api-non-annotated-dependency
(FAST002)](https://docs.astral.sh/ruff/rules/fast-api-non-annotated-dependency/#fast-api-non-annotated-dependency-fast002).
It also re-words the availability section since I found it confusing.

The lint/fix was added in #11579 as always unsafe.
No reasoning is given in the original PR/code as to why this was chosen.
Example of why the fix is unsafe:
https://play.ruff.rs/3bd0566e-1ef6-4cec-ae34-3b07cd308155
```py
from fastapi import Depends, FastAPI, Query

app = FastAPI()

# Fix will remove the parameter default value
@app.get("/items/")
async def read_items(commons: dict = Depends(common_parameters)):
    return commons

# Fix will delete comment and change default parameter value
@app.get("/items/")
async def read_items_1(q: str = Query(  # This comment will be deleted
    default="rick")):
    return q
```
After fixing both instances of `FAST002`:
```py
from fastapi import Depends, FastAPI, Query
from typing import Annotated

app = FastAPI()

# Fix will remove the parameter default value
@app.get("/items/")
async def read_items(commons: Annotated[dict, Depends(common_parameters)]):
    return commons

# Fix will delete comment and change default parameter value
@app.get("/items/")
async def read_items_1(q: Annotated[str, Query()] = "rick"):
    return q

Move big rule implementations (#18931)

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Here's the part that was split out of #18906. I wanted to move these
into the rule files since the rest of the rules in
`deferred_scope`/`statement` have that same structure of implementations
being in the rule definition file. It also resolves the dilemma of where
to put the comment, at least for these rules.

> This could be a good target for a follow-up PR, but we could fold
these `if checker.is_rule_enabled { checker.report_diagnostic` checks
into calls to `checker.report_diagnostic_if_enabled`. I didn't notice
these when adding that method.

This PR folds those calls. I also updated the doc comments by copying
from `report_diagnostic`.

Note: It seems odd to me that the doc comment for `Checker` says
`Diagnostic` while `LintContext` says `OldDiagnostic`, not sure if that
needs a bigger docs change to fix the inconsistency.

Add missing rule code comments (#18906)
<!--
Thank you for contributing to Ruff/ty! To help us out with reviewing,
please consider the following:

- Does this pull request include a summary of the change? (See below.)
- Does this pull request include a descriptive title? (Please prefix
with `[ty]` for ty pull

-->

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

While making some of my other changes, I noticed some of the lints were
missing comments with their lint code/had the wrong numbered lint code.
These comments are super useful since they allow for very easily and
quickly finding the source code of a lint, so I decided to try and
normalize them.

Most of them were fairly straightforward, just adding a doc
comment/comment in the appropriate place.

I decided to make all of the `Pylint` rules have the `PL` prefix.
Previously it was split between no prefix and having prefix, but I
decided to normalize to with prefix since that's what's in the docs, and
the with prefix will show up on no prefix searches, while the reverse is
not true.

I also ran into a lot of rules with implementations in "non-standard"
places (where "standard" means inside a file matching the glob
`crates/ruff_linter/rules/*/rules/**/*.rs` and/or the same rule file
where the rule `struct`/`ViolationMetadata` is defined).

I decided to move all the implementations out of
`crates/ruff_linter/src/checkers/ast/analyze/deferred_scopes.rs` and
into their own files, since that is what the rest of the rules in
`deferred_scopes.rs` did, and those were just the outliers.

There were several rules which I did not end up moving, which you can
see as the extra paths I had to add to my python code besides the
"standard" glob. These rules are generally the error-type rules that
just wrap an error from the parser, and have very small
implementations/are very tightly linked to the module they are in, and
generally every rule of that type was implemented in module instead of
in the "standard" place.

Resolving that requires answering a question I don't think I'm equipped
to handle: Is the point of these comments to give quick access to the
rule definition/docs, or the rule implementation? For all the rules with
implementations in the "standard" location this isn't a problem, as they
are the same, but it is an issue for all of these error type rules. In
the end I chose to leave the implementations where they were, but I'm
not sure if that was the right choice.

Apply fix availability and applicability when adding to `DiagnosticGuard` and remove `NoqaCode::rule` (#18834)
## Summary

This PR removes the last two places we were using `NoqaCode::rule` in
`linter.rs` (see
https://github.com/astral-sh/ruff/pull/18391#discussion_r2154637329 and
https://github.com/astral-sh/ruff/pull/18391#discussion_r2154649726) by
checking whether fixes are actually desired before adding them to a
`DiagnosticGuard`. I implemented this by storing a `Violation`'s `Rule`
on the `DiagnosticGuard` so that we could check if it was enabled in the
embedded `LinterSettings` when trying to set a fix.

All of the corresponding `set_fix` methods on `OldDiagnostic` were now
unused (except in tests where I just set `.fix` directly), so I moved
these to the guard instead of keeping both sets.

The very last place where we were using `NoqaCode::rule` was in the
cache. I just reverted this to parsing the `Rule` from the name. I had
forgotten to update the comment there anyway. Hopefully this doesn't
cause too much of a perf hit.

In terms of binary size, we're back down almost to where `main` was two
days ago
(https://github.com/astral-sh/ruff/pull/18391#discussion_r2155034320):

```
41,559,344 bytes for main 2 days ago
41,669,840 bytes for #18391
41,653,760 bytes for main now (after #18391 merged)
41,602,224 bytes for this branch
```

Only 43 kb up, but that shouldn't all be me this time :)

[`flake8-simplify`] Fix `SIM911` autofix creating a syntax error (#18793)
<!--

- Does this pull request include a descriptive title? (Please prefix

## Summary
The fix would create a syntax error if there wasn't a space between the
`in` keyword and the following expression.
For example:
```python
for country, stars in(zip)(flag_stars.keys(), flag_stars.values()):...
```

I also noticed that the tests for `SIM911` were note being run, so I
fixed that.

Fixes #18776

A little bit of cleanup for consistency's sake: we move all the helpers

Avoid generating diagnostics with per-file ignores (#18801)
## Summary

This PR avoids one of the three calls to `NoqaCode::rule` from
https://github.com/astral-sh/ruff/pull/18391 by applying per-file
ignores in the `LintContext`. To help with this, it also replaces all
direct uses of `LinterSettings.rules.enabled` with a
`LintContext::enabled` (or `Checker::enabled`, which defers to its
context) method. There are still some direct accesses to
`settings.rules`, but as far as I can tell these are not in a part of
the code where we can really access a `LintContext`. I believe all of
the code reachable from `check_path`, where the replaced per-file ignore
code was, should be converted to the new methods.

## Test Plan

Existing tests, with a single snapshot updated for RUF100, which I think
actually shows a more accurate diagnostic message now.

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

While reading the docs I noticed this paragraph on `PERF401`. It was
added in the same PR that the bug with `:=` was fixed, #15050, but don't
know why it was added. The fix should already take care of adding the
parenthesis, so having this paragraph in the docs is just confusing
since it sounds like the user has to do something.

[`pylint`] Avoid flattening nested `min`/`max` when outer call has single argument (`PLW3301`) (#16885)
## Summary

Fixes false positives (and incorrect autofixes) in `nested-min-max`
(`PLW3301`) when the outer `min`/`max` call only has a single argument.
Previously the rule would flatten:

```python
min(min([2, 3], [4, 1]))
```

into `min([2, 3], [4, 1])`, changing the semantics. The rule now skips
any nested call when the outer call has only one positional argument.
The pylint fixture and snapshot were updated accordingly.

## Test Plan

Ran Ruff against the updated `nested_min_max.py` fixture:

```shell
cargo run -p ruff -- check crates/ruff_linter/resources/test/fixtures/pylint/nested_min_max.py --no-cache --select=PLW3301 --preview
```

to verify that `min(min([2, 3], [4, 1]))` and `max(max([2, 4], [3, 1]))`
are no longer flagged. Updated the fixture and snapshot; all other
existing warnings remain unchanged. The code compiles and the unit tests
pass.

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Part of #15584

This PR adds a fix safety section to `PIE794`

I could not track down when this rule was initially implemented/made
unsafe due how old it could be + multiple large refactors to `ruff`.

There is no comment/reasoning in the code given for the unsafety.

Here is a code example demonstrating why it should be unsafe, since
removing any of the assignments would change program behavior
[playground](https://play.ruff.rs/01004644-4259-4449-a581-5007cd59846a)
```py
class A:
    x = 1
    x = 2
    print(x)

class B:
    x = print(3)
    x = print(4)

class C:
    x = [1,2,3]
    y = x
    x = y[1]

[`flake8-comprehensions`] Handle template strings for comprehension fixes (#18710)
Essentially this PR ensures that when we do fixes like this:

```diff
- t"{set(f(x) for x in foo)}"
+ t"{ {f(x) for x in foo} }"
```
we are correctly adding whitespace around the braces. 

This logic is already in place for f-strings and just needed to be
generalized to interpolated strings.

Unify `OldDiagnostic` and `Message` (#18391)
Summary
--

This PR unifies the remaining differences between `OldDiagnostic` and
`Message` (`OldDiagnostic` was only missing an optional `noqa_offset`
field) and
replaces `Message` with `OldDiagnostic`.

The biggest functional difference is that the combined `OldDiagnostic`
kind no
longer implements `AsRule` for an infallible conversion to `Rule`. This
was
pretty easy to work around with `is_some_and` and `is_none_or` in the
few places
it was needed. In `LintContext::report_diagnostic_if_enabled` we can
just use
the new `Violation::rule` method, which takes care of most cases.

Most of the interesting changes are in [this
range](8156992540)
before I started renaming.

Test Plan
--

Existing tests

Future Work
--

I think it's time to start shifting some of these fields to the new
`Diagnostic`
kind. I believe we want `Fix` for sure, but I'm less sure about the
others. We
may want to keep a thin wrapper type here anyway to implement a `rule`
method,
so we could leave some of these fields on that too.

Use `LintContext::report_diagnostic_if_enabled` in `check_tokens` (#18769)
## Summary

This PR avoids the `Vec::retain` call in `check_tokens` by checking if
rules are enabled as their diagnostics are constructed.


2a425e43fd/crates/ruff_linter/src/checkers/tokens.rs (L174-L176)

Since `LintContext::report_diagnostic_if_enabled` required a
`LinterSettings`, I added a `settings` field to the context itself
instead of trying to pass it everywhere. This also turned
`LogicalLinesContext` into a trivial wrapper around `LintContext`, so I
just removed it in favor of using `LintContext` directly too.

The diff is a bit smaller with whitespace hidden since many blocks got
moved into something like this:

```rust
if let Some(mut diagnostic) = context.report_diagnostic.enabled(...) {
    // old code
}
```

## Summary
Stabilizes the UP049 rule (private-type-parameter) by moving it from
Preview to Stable.

UP049 detects and fixes the use of private type parameters (those with
leading underscores) in PEP 695 generic classes and functions.

## Test plan
- Verified that UP049 tests pass:
`crates/ruff_linter/src/rules/pyupgrade/mod.rs`
- Ran full test suite with `make test` 
- Confirmed that no test migration was needed as UP049 was already in
the main `rules` test function

flake8-pytest-style](https://github.com/m-burst/flake8-pytest-style/pull/332),
but the corresponding PR has been open for over a month without
activity.

Additionally, this PR provides an unsafe fix for simple cases where the
non-contextmanager form can be transformed into the context manager
form. Examples of supported patterns are listed in `RUF061_raises.py`,
`RUF061_warns.py`, and `RUF061_deprecated_call.py` test files.

The more complex case from the original issue (involving two separate
statements):
```python
excinfo = pytest.raises(ValueError, int, "hello")
assert excinfo.match("^invalid literal")
```
is getting fixed like this:
```python
with pytest.raises(ValueError) as excinfo:
    int("hello")
assert excinfo.match("^invalid literal")
```
Putting match in the raises call requires multi-statement
transformation, which I am not sure how to implement.

## Test Plan

<!-- How was it tested? -->

New test files were added to cover various usages of the
non-contextmanager form of pytest.raises, warns, and deprecated_call.

[`ruff`] Validate arguments before offering a fix (`RUF056`) (#18631)
## Summary

Fixes https://github.com/astral-sh/ruff/issues/18628 by avoiding a fix
if there are "unknown" arguments, including any keyword arguments and
more than the expected 2 positional arguments.

I'm a bit on the fence here because it also seems reasonable to avoid a
diagnostic at all. Especially in the final test case I added (`not
my_dict.get(default=False)`), the hint suggesting to remove
`default=False` seems pretty misleading. At the same time, I guess the
diagnostic at least calls attention to the call site, which could help
to fix the missing argument bug too.

As I commented on the issue, I double-checked that keyword arguments are
invalid as far back as Python 3.8, even though the positional-only
marker was only added to the
[docs](https://docs.python.org/3.11/library/stdtypes.html#dict.get) in
3.12 (link is to 3.11, showing its absence).

## Test Plan

New tests derived from the bug report

## Stabilization

This was planned to be stabilized in 0.12, and the bug is less severe
than some others, but if there's nobody opposed, I will plan **not to
stabilize** this one for now.

Fix false positive in for mutations in return statements (B909) (#18408)
<!--
Thank you for contributing to Ruff/ty! To help us out with reviewing,
please consider the following:

- Does this pull request include a summary of the change? (See below.)
- Does this pull request include a descriptive title? (Please prefix
with `[ty]` for ty pull

-->

## Summary

Fixes false positive in B909 (`loop-iterator-mutation`) where mutations
inside return/break statements were incorrectly flagged as violations.
The fix adds tracking for when mutations occur within return/break
statements and excludes them from violation detection, as they don't
cause the iteration issues B909 is designed to prevent.



## Test Plan

- Added test cases covering the reported false positive scenarios to
`B909.py`
  - Verified existing B909 tests continue to pass (no regressions)
  - Ran `cargo test -p ruff_linter --lib flake8_bugbear` successfully

[ty] AST garbage collection (#18482)
## Summary

Garbage collect ASTs once we are done checking a given file. Queries
with a cross-file dependency on the AST will reparse the file on demand.
This reduces ty's peak memory usage by ~20-30%.

The primary change of this PR is adding a `node_index` field to every
AST node, that is assigned by the parser. `ParsedModule` can use this to
create a flat index of AST nodes any time the file is parsed (or
reparsed). This allows `AstNodeRef` to simply index into the current
instance of the `ParsedModule`, instead of storing a pointer directly.

The indices are somewhat hackily (using an atomic integer) assigned by
the `parsed_module` query instead of by the parser directly. Assigning
the indices in source-order in the (recursive) parser turns out to be
difficult, and collecting the nodes during semantic indexing is
impossible as `SemanticIndex` does not hold onto a specific
`ParsedModuleRef`, which the pointers in the flat AST are tied to. This
means that we have to do an extra AST traversal to assign and collect
the nodes into a flat index, but the small performance impact (~3% on
cold runs) seems worth it for the memory savings.

[`ruff`] Handle extra arguments to `deque` (`RUF037`) (#18614)
## Summary

Fixes https://github.com/astral-sh/ruff/issues/18612 by:
- Bailing out without a fix in the case of `*args`, which I don't think
we can fix reliably
- Using an `Edit::deletion` from `remove_argument` instead of an
`Edit::range_replacement` in the presence of unrecognized keyword
arguments

I thought we could always switch to the `Edit::deletion` approach
initially, but it caused problems when `maxlen` was passed positionally,
which we didn't have any existing tests for.

The replacement fix can easily delete comments, so I also marked the fix
unsafe in these cases and updated the docs accordingly.

## Test Plan

New test cases derived from the issue.

## Stabilization

These are pretty significant changes, much like those to PYI059 in
https://github.com/astral-sh/ruff/pull/18611 (and based a bit on the
implementation there!), so I think it probably makes sense to
un-stabilize this for the 0.12 release, but I'm open to other thoughts
there.

[`refurb`] Add a note about float literal handling (`FURB157`) (#18615)
Summary
--

Updates the rule docs to explicitly state how cases like
`Decimal("0.1")` are handled (not affected) because the discussion of
"float casts" referring to values like `nan` and `inf` is otherwise a
bit confusing.

These changes are based on suggestions from @AlexWaygood on Notion, with
a slight adjustment to use 0.1 instead of 0.5 since it causes a more
immediate issue in the REPL:

```pycon
>>> from decimal import Decimal
>>> Decimal(0.5) == Decimal("0.5")
True
>>> Decimal(0.1) == Decimal("0.1")
False
```

[`flake8-pyi`] Avoid syntax error in the case of starred and keyword arguments (`PYI059`) (#18611)
## Summary

Fixes https://github.com/astral-sh/ruff/issues/18602 by:
1. Avoiding a fix when `*args` are present
2. Inserting the `Generic` base class right before the first keyword
argument, if one is present

In an intermediate commit, I also had special handling to avoid a fix in
the `**kwargs` case, but this is treated (roughly) as a normal keyword,
and I believe handling it properly falls out of the other keyword fix.

I also updated the `add_argument` utility function to insert new
arguments right before the keyword argument list instead of at the very
end of the argument list. This changed a couple of snapshots unrelated
to `PYI059`, but there shouldn't be any functional changes to other
rules because all other calls to `add_argument` were adding a keyword
argument anyway.

[`refurb`] Parenthesize lambda and ternary expressions in iter (`FURB122`, `FURB142`) (#18592)
Summary
--

Fixes #18590 by adding parentheses around lambdas and if expressions in
`for` loop iterators for FURB122 and FURB142. I also updated the docs on
the helper function to reflect the part actually being parenthesized and
the new checks.

The `lambda` case actually causes a `TypeError` at runtime, but I think
it's still worth handling to avoid causing a syntax error.

```pycon
>>> s = set()
... for x in (1,) if True else (2,):
...     s.add(-x)
... for x in lambda: 0:
...     s.discard(-x)
...
Traceback (most recent call last):
  File "<python-input-0>", line 4, in <module>
    for x in lambda: 0:

Remove `Message::to_rule` (#18447)
## Summary

As the title says, this PR removes the `Message::to_rule` method by
replacing related uses of `Rule` with `NoqaCode` (or the rule's name in
the case of the cache). Where it seemed a `Rule` was really needed, we
convert back to the `Rule` by parsing either the rule name (with
`str::parse`) or the `NoqaCode` (with `Rule::from_code`).

I thought this was kind of like cheating and that it might not resolve
this part of Micha's
[comment](https://github.com/astral-sh/ruff/pull/18391#issuecomment-2933764275):

> because we can't add Rule to Diagnostic or **have it anywhere in our
shared rendering logic**

but after looking again, the only remaining `Rule` conversion in
rendering code is for the SARIF output format. The other two non-test
`Rule` conversions are for caching and writing a fix summary, which I
don't think fall into the shared rendering logic. That leaves the SARIF
format as the only real problem, but maybe we can delay that for now.

The motivation here is that we won't be able to store a `Rule` on the
new `Diagnostic` type, but we should be able to store a `NoqaCode`,
likely as a string.

## Summary

Mark `FURB180`'s fix as unsafe if the class already has base classes.
This is because the base classes might validate the other base classes

[`fastapi`] Avoid false positive for class dependencies (`FAST003`) (#18271)
<!--
Thank you for contributing to Ruff/ty! To help us out with reviewing,
please consider the following:

- Does this pull request include a summary of the change? (See below.)
- Does this pull request include a descriptive title? (Please prefix
with `[ty]` for ty pull
  requests.)
- Does this pull request include references to any relevant issues?
-->

## Summary

Closes #17226.

This PR updates the `FAST003` rule to correctly handle [FastAPI class
dependencies](https://fastapi.tiangolo.com/tutorial/dependencies/classes-as-dependencies/).
Specifically, if a path parameter is declared in either:

- a `pydantic.BaseModel` used as a dependency, or  
- the `__init__` method of a class used as a dependency,  

then `FAST003` will no longer incorrectly report it as unused.

FastAPI allows a shortcut when using annotated class dependencies -
`Depends` can be called without arguments, e.g.:

```python
class MyParams(BaseModel):
    my_id: int

@router.get("/{my_id}")
def get_id(params: Annotated[MyParams, Depends()]): ...
```
This PR ensures that such usage is properly supported by the linter.

Note: Support for dataclasses is not included in this PR. Let me know if
you’d like it to be added.

## Test Plan

Added relevant test cases to the `FAST003.py` fixture.

Add a `SourceFile` to `OldDiagnostic` (#18356)
Summary
--

This is the last main difference between the `OldDiagnostic` and
`Message`
types, so attaching a `SourceFile` to `OldDiagnostic` should make
combining the
two types almost trivial.

Initially I updated the remaining rules without access to a `Checker` to
take a
`&SourceFile` directly, but after Micha's suggestion in
https://github.com/astral-sh/ruff/pull/18356#discussion_r2113281552, I
updated all of these calls to take a
`LintContext` instead. This new type is a thin wrapper around a
`RefCell<Vec<OldDiagnostic>>`
and a `SourceFile` and now has the `report_diagnostic` method returning
a `DiagnosticGuard` instead of `Checker`.
This allows the same `Drop`-based implementation to be used in cases
without a `Checker` and also avoids a lot of intermediate allocations of
`Vec<OldDiagnostic>`s.

`Checker` now also contains a `LintContext`, which it defers to for its
`report_diagnostic` methods, which I preserved for convenience.

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Add utility functions `generate_import_edit` and
`generate_remove_and_runtime_import_edit` to generate the fix needed for
the airflow rules.

1. `generate_import_edit` is for the cases where the member name has
changed. (e.g., `airflow.datasts.Dataset` to `airflow.sdk.Asset`) It's
just extracted from the original logic
2. `generate_remove_and_runtime_import_edit` is for cases where the
member name has not changed. (e.g.,
`airflow.operators.pig_operator.PigOperator` to
`airflow.providers.apache.pig.hooks.pig.PigCliHook`) This is newly
introduced. As it introduced runtime import, I mark it as an unsafe fix.
Under the hook, it tried to find the original import statement, remove
it, and add a new import fix

[`pylint`] Implement `missing-maxsplit-arg` (`PLC0207`) (#17454)
## Summary

Implements  `use-maxsplit-arg` (`PLC0207`)

https://pylint.readthedocs.io/en/latest/user_guide/messages/convention/use-maxsplit-arg.html
> Emitted when accessing only the first or last element of str.split().
The first and last element can be accessed by using str.split(sep,
maxsplit=1)[0] or str.rsplit(sep, maxsplit=1)[-1] instead.

This is part of https://github.com/astral-sh/ruff/issues/970

## Test Plan

`cargo test`

Additionally compared Ruff output to Pylint:
```
pylint --disable=all --enable=use-maxsplit-arg crates/ruff_linter/resources/test/fixtures/pylint/missing_maxsplit_arg.py

cargo run -p ruff -- check crates/ruff_linter/resources/test/fixtures/pylint/missing_maxsplit_arg.py --no-cache --select PLC0207

[`flake8-bugbear `] Add fix safety section (`B006`) (#17652)
## Summary

This PR add the `fix safety` section for rule `B006` in
`mutable_argument_default.rs` for #15584

When applying this rule for fixes, certain changes may alter the
original logical behavior. For example:

before:
```python
def cache(x, storage=[]):
    storage.append(x)
    return storage

print(cache(1))  # [1]
print(cache(2))  # [1, 2]
```

after:
```python
def cache(x, storage=[]):
    storage.append(x)
    return storage

print(cache(1))  # [1]
print(cache(2))  # [2]
```

Add a `ViolationMetadata::rule` method (#18234)
Summary
--

This PR adds a macro-generated method to retrieve the `Rule` associated
with a given `Violation` struct, which makes it substantially cheaper
than parsing from the rule name. The rule is then converted to a
`NoqaCode` for storage on the `Message` (and eventually on the new
diagnostic type). The `ViolationMetadata::rule_name` method was now
unused, so the `rule` method replaces it.

Several types had to be moved from the `ruff_diagnostics` crate to the
`ruff_linter` crate to make this work, namely the `Violation` traits and
the old `Diagnostic` type, which had a constructor generic over a
`Violation`.

It's actually a fairly small PR, minus the hundreds of import changes.
The main changes are in these files:

Return `DiagnosticGuard` from `Checker::report_diagnostic` (#18232)
Summary
--

This PR adds a `DiagnosticGuard` type to ruff that is adapted from the
`DiagnosticGuard` and `LintDiagnosticGuard` types from ty. This guard is
returned by `Checker::report_diagnostic` and derefs to a
`ruff_diagnostics::Diagnostic` (`OldDiagnostic`), allowing methods like
`OldDiagnostic::set_fix` to be called on the result. On `Drop` the
`DiagnosticGuard` pushes its contained `OldDiagnostic` to the `Checker`.

The main motivation for this is to make a following PR adding a
`SourceFile` to each diagnostic easier. For every rule where a `Checker`
is available, this will now only require modifying
`Checker::report_diagnostic` rather than all the rules.

In the few cases where we need to create a diagnostic before we know if
we actually want to emit it, there is a `DiagnosticGuard::defuse`
method, which consumes the guard without emitting the diagnostic. I was
able to restructure about half of the rules that naively called this to
avoid calling it, but a handful of rules still need it.

One of the fairly common patterns where `defuse` was needed initially
was something like

```rust
let diagnostic = Diagnostic::new(DiagnosticKind, range);

if !checker.enabled(diagnostic.rule()) {
    return;
}
```

So I also added a `Checker::checked_report_diagnostic` method that
handles this check internally. That helped to avoid some additional
`defuse` calls. The name is a bit repetitive, so I'm definitely open to
suggestions there. I included a warning against using it in the docs
since, as we've seen, the conversion from a diagnostic to a rule is
actually pretty expensive.

Remove `Checker::report_diagnostics` (#18206)
Summary
--

I thought that emitting multiple diagnostics at once would be difficult
to port to a diagnostic construction model closer to ty's
`InferContext::report_lint`, so as a first step toward that, this PR
removes `Checker::report_diagnostics`.

In many cases I was able to do some related refactoring to avoid
allocating a `Vec<Diagnostic>` at all, often by adding a `Checker` field
to a `Visitor` or by passing a `Checker` instead of a `&mut
Vec<Diagnostic>`.

In other cases, I had to fall back on something like

```rust
for diagnostic in diagnostics {
    checker.report_diagnostic(diagnostic);
}
```

which I guess is a bit worse than the `extend` call in
`report_diagnostics`, but hopefully it won't make too much of a
difference.

I'm still not quite sure what to do with the remaining loop cases. The
two main use cases for collecting a sequence of diagnostics before
emitting any of them are:

1. Applying a single `Fix` to a group of diagnostics
2. Avoiding an earlier diagnostic if something goes wrong later

I was hoping we could get away with just a `DiagnosticGuard` that
reported a `Diagnostic` on drop, but I guess we will still need a
`DiagnosticGuardBuilder` that can be collected in these cases and
produce a `DiagnosticGuard` once we know we actually want the
diagnostics.

### Unsafe Fix Example

```python

    global called
    called += 1
    if called == 1:
    # after first call we change the method
        def new_predicate(_): return False
        globals()['predicate'] = new_predicate
    return True

def foo():
    for item in range(10):
        if predicate(item):
            return True
    return False

def foo_gen():
    return any(predicate(item) for item in range(10))

called = 0
print(foo())      # true – returns immediately on first call

called = 0
print(foo_gen())  # false – second call uses new `predicate`
```

### Note

I notice that
[here](46be305ad2/crates/ruff_linter/src/rules/flake8_simplify/rules/reimplemented_builtin.rs (L60))
we have two rules, `SIM110` & `SIM111`. The second one seems not anymore
active. Should I delete `SIM111`?

Unify `Message` variants (#18051)
## Summary

This PR unifies the ruff `Message` enum variants for syntax errors and
rule violations into a single `Message` struct consisting of a shared
`db::Diagnostic` and some additional, optional fields used for some rule
violations.

This version of `Message` is nearly a drop-in replacement for
`ruff_diagnostics::Diagnostic`, which is the next step I have in mind
for the refactor.

I think this is also a useful checkpoint because we could possibly add
some of these optional fields to the new `Diagnostic` type. I think
we've previously discussed wanting support for `Fix`es, but the other
fields seem less relevant, so we may just need to preserve the `Message`
wrapper for a bit longer.

Inline `DiagnosticKind` into other diagnostic types (#18074)
## Summary

This PR deletes the `DiagnosticKind` type by inlining its three fields
(`name`, `body`, and `suggestion`) into three other diagnostic types:
`Diagnostic`, `DiagnosticMessage`, and `CacheMessage`.

Instead of deferring to an internal `DiagnosticKind`, both `Diagnostic`
and `DiagnosticMessage` now have their own macro-generated `AsRule`
implementations.

This should make both https://github.com/astral-sh/ruff/pull/18051 and
another follow-up PR changing the type of `name` on `CacheMessage`
easier since its type will be able to change separately from
`Diagnostic` and `DiagnosticMessage`.

[`flake8-simplify`] Correct behavior for `str.split`/`rsplit` with `maxsplit=0` (`SIM905`) (#18075)
Fixes #18069

<!--

- Does this pull request include a descriptive title? (Please prefix
with `[ty]` for ty pull

-->

## Summary

This PR addresses a bug in the `flake8-simplify` rule `SIM905`
(split-static-string) where `str.split(maxsplit=0)` and
`str.rsplit(maxsplit=0)` produced incorrect results for empty strings or
strings starting/ending with whitespace. The fix ensures that the
linting rule's suggested replacements now align with Python's native
behavior for these specific `maxsplit=0` scenarios.

## Test Plan

1. Added new test cases to the existing
`crates/ruff_linter/resources/test/fixtures/flake8_simplify/SIM905.py`
fixture to cover the scenarios described in issue #18069.
2.  Ran `cargo test -p ruff_linter`.
3. Verified and accepted the updated snapshots for `SIM905.py` using
`cargo insta review`. The new snapshots confirm the corrected behavior
for `maxsplit=0`.

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Similiar to https://github.com/astral-sh/ruff/pull/17941.

`Replacement::Name` was designed for linting only. Now, we also want to
fix the user code. It would be easier to replace it with a better
AutoImport struct whenever possible.

On the other hand, `AIR301` and `AIR311` contain attribute changes that
can still use a struct like `Replacement::Name`. To reduce the
confusion, I also updated it as `Replacement::AttrName`

Some of the original `Replacement::Name` has been replaced as
`Replacement::Message` as they're not directly mapping and the message
has now been moved to `help`

[`ruff`] add fix safety section (`RUF007`) (#17755)
The PR add the `fix safety` section for rule `RUF007` (#15584 )

It seems that the fix was always marked as unsafe #14401

## Unsafety example

This first example is a little extreme. In fact, the class `Foo`
overrides the `__getitem__` method but in a very special, way. The
difference lies in the fact that `zip(letters, letters[1:])` call the
slice `letters[1:]` which is behaving weird in this case, while
`itertools.pairwise(letters)` call just `__getitem__(0), __getitem__(1),
...` and so on.

Note that the diagnostic is emitted: [playground](https://play.ruff.rs)

I don't know if we want to mention this problem, as there is a subtile
bug in the python implementation of `Foo` which make the rule unsafe.

```python
from dataclasses import dataclass
import itertools

@dataclass
class Foo:
    letters: str
    
    def __getitem__(self, index):
        return self.letters[index] + "_foo"


letters = Foo("ABCD")
zip_ = zip(letters, letters[1:])
for a, b in zip_:
    print(a, b) # A_foo B, B_foo C, C_foo D, D_foo _
    
pair = itertools.pairwise(letters)
for a, b in pair:
    print(a, b) # A_foo B_foo, B_foo C_foo, C_foo D_foo
```

This other example is much probable.
here, `itertools.pairwise` was shadowed by a costume function
[(playground)](https://play.ruff.rs)

```python
from dataclasses import dataclass
from itertools import pairwise

def pairwise(a):
    return []
    
letters = "ABCD"
zip_ = zip(letters, letters[1:])
print([(a, b) for a, b in zip_]) # [('A', 'B'), ('B', 'C'), ('C', 'D')]

pair = pairwise(letters)
print(pair) # []
```

[`pyupgrade`] Add `resource.error` as deprecated alias of `OSError` (`UP024`) (#17933)
## Summary

Partially addresses #17935.


[`resource.error`](https://docs.python.org/3/library/resource.html#resource.error)
is a deprecated alias of
[`OSError`](https://docs.python.org/3/library/exceptions.html#OSError).
> _Changed in version 3.3:_ Following [**PEP
3151**](https://peps.python.org/pep-3151/), this class was made an alias
of
[`OSError`](https://docs.python.org/3/library/exceptions.html#OSError).

Add it to the list of `OSError` aliases found by [os-error-alias
(UP024)](https://docs.astral.sh/ruff/rules/os-error-alias/#os-error-alias-up024).

## Test Plan

Sorry, I usually don't program in Rust. Could you at least point me to
the test I would need to modify?

[`airflow`] Apply try-catch guard to all AIR3 rules (`AIR3`) (#17887)
<!--
Thank you for contributing to Ruff! To help us out with reviewing,
please consider the following:

- Does this pull request include a summary of the change? (See below.)
- Does this pull request include a descriptive title?
- Does this pull request include references to any relevant issues?
-->

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

If a try-catch block guards the names, we don't raise warnings. During
this change, I discovered that some of the replacement types were
missed. Thus, I extend the fix to types other than AutoImport as well

## Test Plan

<!-- How was it tested? -->

Test fixtures are added and updated.

[`ruff`] Implement a recursive check for `RUF060` (#17976)
<!--
Thank you for contributing to Ruff! To help us out with reviewing,
please consider the following:

- Does this pull request include a summary of the change? (See below.)
- Does this pull request include a descriptive title?
- Does this pull request include references to any relevant issues?
-->

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->
The existing implementation of RUF060 (InEmptyCollection) is not
recursive, meaning that although set([]) results in an empty collection,
the existing code fails it because set is taking an argument.

The updated implementation allows set and frozenset to take empty
collection as positional argument (which results in empty
set/frozenset).

## Test Plan

Added test cases for recursive cases + updated snapshot (see RUF060.py).

[`refurb`] Mark autofix as safe only for number literals in `FURB116` (#17692)
<!--

please consider the following:

- Does this pull request include a summary of the change? (See below.)
- Does this pull request include a descriptive title?
- Does this pull request include references to any relevant issues?
-->

## Summary
We can only guarantee the safety of the autofix for number literals, all
other cases may change the runtime behaviour of the program or introduce
a syntax error. For the cases reported in the issue that would result in
a syntax error, I disabled the autofix.

Follow-up of #17661. 

Fixes #16472.
