[`flake8-pyi`] Expand `Optional[A]` to `A | None` (`PYI016`) (#18572)
## Summary
Under preview 🧪 I've expanded rule `PYI016` to also flag type
union duplicates containing `None` and `Optional`.

## Test Plan
Examples/tests have been added. I've made sure that the existing
examples did not change unless preview is enabled.

## Relevant Issues
* https://github.com/astral-sh/ruff/issues/18508 (discussing
introducing/extending a rule to flag `Optional[None]`)
* https://github.com/astral-sh/ruff/issues/18546 (where I discussed this
addition with @AlexWaygood)

[`pylint`] Allow fix with comments and document performance implications (`PLW3301`) (#18936)
Summary
--

Closes #18849 by adding a `## Known issues` section describing the
potential performance issues when fixing nested iterables. I also
deleted the comment check since the fix is already unsafe and added a
note to the `## Fix safety` docs.

Test Plan
--

Existing tests, updated to allow a fix when comments are present since
the fix is already unsafe.

This PR expands PGH005 to also check for AsyncMock methods in the same

the corresponding async assertions `assert mock.not_awaited()`.

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

## 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

| float`, which raises a `TypeError` when executed.

The fix consists of making sure that the merged super-type is inserted
where the first type that is merged was before.

## Test Plan
Tests have been expanded with examples from the issue.

figured that is not possible yet...

[`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.

Essentially this PR ensures that when we do fixes like this:

+ 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.

[`ruff`] Check for non-context-manager use of `pytest.raises`, `pytest.warns`, and `pytest.deprecated_call` (`RUF061`) (#17368)
<!--
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?
-->

This PR aims to close #16605.

## Summary

This PR introduces a new rule (`RUF061`) that detects non-contextmanager
usage of `pytest.raises`, `pytest.warns`, and `pytest.deprecated_call`.
This pattern is discouraged and [was proposed in
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)
<!--

## 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

Fixes #18399

[`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.

[`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.

## Test Plan

Existing PYI059 cases, plus new tests based on the issue

[`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:
             ^^^^^^^^^
TypeError: 'function' object is not iterable
```

[`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.)

-->

## 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.

## 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

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

<!--
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

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`

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

- 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

[`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 fix as safe for `readlines-in-for` (`FURB129`) (#17644)
This PR promotes the fix applicability of [readlines-in-for
(FURB129)](https://docs.astral.sh/ruff/rules/readlines-in-for/#readlines-in-for-furb129)
to always safe.

In the original PR (https://github.com/astral-sh/ruff/pull/9880), the
author marked the rule as unsafe because Ruff's type inference couldn't
quite guarantee that we had an `IOBase` object in hand. Some false
positives were recorded in the test fixture. However, before the PR was
merged, Charlie added the necessary type inference and the false
positives went away.

According to the [Python
documentation](https://docs.python.org/3/library/io.html#io.IOBase), I
believe this fix is safe for any proper implementation of `IOBase`:

>[IOBase](https://docs.python.org/3/library/io.html#io.IOBase) (and its
subclasses) supports the iterator protocol, meaning that an
[IOBase](https://docs.python.org/3/library/io.html#io.IOBase) object can
be iterated over yielding the lines in a stream. Lines are defined
slightly differently depending on whether the stream is a binary stream
(yielding bytes), or a text stream (yielding character strings). See
[readline()](https://docs.python.org/3/library/io.html#io.IOBase.readline)
below.

and then in the [documentation for
`readlines`](https://docs.python.org/3/library/io.html#io.IOBase.readlines):

>Read and return a list of lines from the stream. hint can be specified
to control the number of lines read: no more lines will be read if the
total size (in bytes/characters) of all lines so far exceeds hint. [...]
>Note that it’s already possible to iterate on file objects using for
line in file: ... without calling file.readlines().

I believe that a careful reading of our [versioning
policy](https://docs.astral.sh/ruff/versioning/#version-changes)
requires that this change be deferred to a minor release - but please
correct me if I'm wrong!

[`pylint`] Detect `global` declarations in module scope (`PLE0118`) (#17411)
Summary
--

While going through the syntax errors in [this comment], I was surprised
to see the error `name 'x' is assigned to before global declaration`,
which corresponds to [load-before-global-declaration (PLE0118)] and has
also been reimplemented as a syntax error (#17135). However, it looks
like neither of the implementations consider `global` declarations in
the top-level module scope, which is a syntax error in CPython:

```python
# try.py
x = None
global x
```

```shell
> python -m compileall -f try.py
Compiling 'try.py'...
***   File "try.py", line 2
    global x
    ^^^^^^^^
SyntaxError: name 'x' is assigned to before global declaration
```

I'm not sure this is the best or most elegant solution, but it was a
quick fix that passed all of our tests.

[`perflint`] Implement fix for `manual-dict-comprehension` (`PERF403`) (#16719)
## Summary

This change adds an auto-fix for manual dict comprehensions. It also
copies many of the improvements from #13919 (and associated PRs fixing
issues with it), and moves some of the utility functions from
`manual_list_comprehension.rs` into a separate `helpers.rs` to be used
in both.

## Test Plan

I added a preview test case to showcase the new fix and added a test
case in `PERF403.py` to make sure lines with semicolons function. I
didn't yet make similar tests to the ones I added earlier to
`PERF401.py`, but the logic is the same, so it might be good to add
those to make sure they work.

[syntax-errors] `await` outside async functions (#17363)
Summary
--

This PR implements detecting the use of `await` expressions outside of
async functions. This is a reimplementation of
[await-outside-async
(PLE1142)](https://docs.astral.sh/ruff/rules/await-outside-async/) as a
semantic syntax error.

Despite the rule name, PLE1142 also applies to `async for` and `async
with`, so these are covered here too.

Test Plan
--

Existing PLE1142 tests.

I also deleted more code from the `SemanticSyntaxCheckerVisitor` to
avoid changes in other parser tests.

[`flake8-pie`] Avoid false positive for multiple assignment with `auto()` (`PIE796`) (#17274)
This fix closes #16868 

I noticed the issue is assigned, but the assignee appears to be actively
working on another pull request. I hope that’s okay!

<!--
Thank you for contributing to Ruff! To help us out with reviewing,
please consider the following:

-->

## Summary

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

As of Python 3.11.1, `enum.auto()` can be used in multiple assignments.
This pattern should not trigger non-unique-enums check.
Reference: [Python docs on
enum.auto()](https://docs.python.org/3/library/enum.html#enum.auto)

This fix updates the check logic to skip enum variant statements where
the right-hand side is a tuple containing a call to `enum.auto()`.

## Test Plan

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

The added test case uses the example from the original issue. It
previously triggered a false positive, but now passes successfully.

[syntax-errors] Async comprehension in sync comprehension (#17177)
Summary
--

Detect async comprehensions nested in sync comprehensions in async
functions before Python 3.11, when this was [changed].

The actual logic of this rule is very straightforward, but properly
tracking the async scopes took a bit of work. An alternative to the
current approach is to offload the `in_async_context` check into the
`SemanticSyntaxContext` trait, but that actually required much more
extensive changes to the `TestContext` and also to ruff's semantic
model, as you can see in the changes up to
31554b473507034735bd410760fde6341d54a050. This version has the benefit
of mostly centralizing the state tracking in `SemanticSyntaxChecker`,
although there was some subtlety around deferred function body traversal
that made the changes to `Checker` more intrusive too (hence the new
linter test).

The `Checkpoint` struct/system is obviously overkill for now since it's
only tracking a single `bool`, but I thought it might be more useful
later.

[changed]: https://github.com/python/cpython/issues/77527

Test Plan
--

New inline tests and a new linter integration test.

[`airflow`] Expand module path check to individual symbols (`AIR302`) (#17278)
## Summary

### Improvement
Expand the following moved module into individual symbols.

* airflow.triggers.temporal
* airflow.triggers.file
* airflow.triggers.external_task
* airflow.hooks.subprocess
* airflow.hooks.package_index
* airflow.hooks.filesystem
* airflow.sensors.weekday
* airflow.sensors.time_delta
* airflow.sensors.time_sensor
* airflow.sensors.date_time
* airflow.operators.weekday
* airflow.operators.datetime
* airflow.operators.bash 

This removes `Replacement::ImportPathMoved`.

## Fix
During the expansion, the following paths were also fixed

* airflow.sensors.s3_key_sensor.S3KeySensor →
airflow.providers.amazon.aws.sensors.S3KeySensor
* airflow.operators.sql.SQLThresholdCheckOperator →
airflow.providers.common.sql.operators.sql.SQLThresholdCheckOperator
* airflow.hooks.druid_hook.DruidDbApiHook →
airflow.providers.apache.druid.hooks.druid.DruidDbApiHook
* airflow.hooks.druid_hook.DruidHook →
airflow.providers.apache.druid.hooks.druid.DruidHook
* airflow.kubernetes.pod_generator.extend_object_field →
airflow.providers.cncf.kubernetes.pod_generator.extend_object_field
* airflow.kubernetes.pod_launcher.PodLauncher →
airflow.providers.cncf.kubernetes.pod_launcher_deprecated.PodLauncher
* airflow.kubernetes.pod_launcher.PodStatus →
airflow.providers.cncf.kubernetes.pod_launcher_deprecated.PodStatus
* airflow.kubernetes.pod_generator.PodDefaults →
airflow.providers.cncf.kubernetes.pod_generator.PodDefaults
* airflow.kubernetes.pod_launcher_deprecated.PodDefaults →
airflow.providers.cncf.kubernetes.pod_launcher_deprecated.PodDefaults

### Refactor
As many symbols are moved into the same module,
`SourceModuleMovedToProvider` is introduced for grouping similar logic

[`flake8-pytest-style`] Avoid false positive for legacy form of `pytest.raises` (`PT011`) (#17231)
This fix closes #17026 

## Summary

The check for the `PytestRaisesTooBroad` rule is now skipped if there is
a second positional argument present, which means `pytest.raises` is
used as a function.

## Test Plan

Tested on the example from the issue, which now passes the check.
```Python3
pytest.raises(Exception, func, *func_args, **func_kwargs).match("error message")
```

Fix RUF100 to detect unused file-level noqa directives with specific codes (#17042) (#17061)
Closes #17042

## Summary
This PR fixes the issue outlined in #17042 where RUF100 (unused-noqa)
fails to detect unused file-level noqa directives (`# ruff: noqa` or `#
ruff: noqa: {code}`).

The issue stems from two underlying causes:

1. For blanket file-level directives (`# ruff: noqa`), there's a
circular dependency: the directive exempts all rules including RUF100
itself, which prevents checking for usage. This isn't changed by this
PR. I would argue it is intendend behavior - a blanket `# ruff: noqa`
directive should exempt all rules including RUF100 itself.

2. For code-specific file-level directives (e.g. `# ruff: noqa: F841`),
the handling was missing in the `check_noqa` function. This is added in
this PR.

## Notes
- For file-level directives, the `matches` array is pre-populated with
the specified codes during parsing, unlike line-level directives which
only populate their `matches` array when actually suppressing
diagnostics. This difference requires the somewhat clunky handling of
both cases. I would appreciate guidance on a cleaner design :)

- A more fundamental solution would be to change how file-level
directives initialize the `matches` array in
`FileNoqaDirectives::extract()`, but that requires more substantial
changes as it breaks existing functionality. I suspect discussions in
#16483 are relevant for this.

## Test Plan
- Local verification
- Added a test case and fixture

Implement `Invalid rule provided` as rule RUF102 with `--fix` (#17138)
<!--
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?
-->

Closes #17084

## Summary
This PR adds a new rule (RUF102) to detect and fix invalid rule codes in
`noqa` comments.
Invalid rule codes in `noqa` directives serve no purpose and may
indicate outdated code suppressions.

This extends the previous behaviour originating from
`crates/ruff_linter/src/noqa.rs` which would only emit a warnigs.
With this rule a `--fix` is available.

The rule:
1. Analyzes all `noqa` directives to identify invalid rule codes
2. Provides autofix functionality to:
   - Remove the entire comment if all codes are invalid
   - Remove only the invalid codes when mixed with valid codes
3. Preserves original comment formatting and whitespace where possible

Example cases:
- `# noqa: XYZ111` → Remove entire comment (keep empty line)
- `# noqa: XYZ222, XYZ333` → Remove entire comment (keep empty line)
-  `# noqa: F401, INVALID123` → Keep only valid codes (`# noqa: F401`)

## Test Plan
- Added tests in
`crates/ruff_linter/resources/test/fixtures/ruff/RUF102.py` covering
different example cases.

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

## Notes 
- This does not handle cases where parsing fails. E.g. `# noqa:
NON_EXISTENT, ANOTHER_INVALID` causes a `LexicalError` and the
diagnostic is not propagated and we cannot handle the diagnostic. I am
also unsure what proper `fix` handling would be and making the user
aware we don't understand the codes is probably the best bet.
- The rule is added to the Preview rule group as it's a new addition

## Questions
- Should we remove the warnings, now that we have a rule?
- Is the current fix behavior appropriate for all cases, particularly
the handling of whitespace and line deletions?
- I'm new to the codebase; let me know if there are rule utilities which
could have used but didn't.

Control flow: `return` and `raise` (#17121)
We add support for `return` and `raise` statements in the control flow
graph: we simply add an edge to the terminal block, push the statements
to the current block, and proceed.

This implementation will have to be modified somewhat once we add
support for `try` statements - then we will need to check whether to
_defer_ the jump. But for now this will do!

Also in this PR: We fix the `unreachable` diagnostic range so that it
lumps together consecutive unreachable blocks.

[`airflow`] Move `AIR302` to `AIR301` and `AIR303` to `AIR302` (#17151)
## Summary

Following up the discussion in
https://github.com/astral-sh/ruff/issues/14626#issuecomment-2766548545,
we're to reorganize airflow rules. Before this discussion happens, we
combine required changes and suggested changes in to one single error
code.

This PR first rename the original error code to the new error code as we
discussed. We will gradually extract suggested changes out of AIR301 and
AIR302 to AIR311 and AIR312 in the following PRs

## Test Plan

Except for file, error code rename, the test case should work as it used
to be.

Control flow graph: setup (#17064)
This PR contains the scaffolding for a new control flow graph
implementation, along with its application to the `unreachable` rule. At
the moment, the implementation is a maximal over-approximation: no
control flow is modeled and all statements are counted as reachable.
With each additional statement type we support, this approximation will
improve.

So this PR just contains:
- A `ControlFlowGraph` struct and builder
- Support for printing the flow graph as a Mermaid graph
- Snapshot tests for the actual graphs
- (a very bad!) reimplementation of `unreachable` using the new structs
- Snapshot tests for `unreachable`

# Instructions for Viewing Mermaid snapshots
Unfortunately I don't know how to convince GitHub to render the Mermaid
graphs in the snapshots. However, you can view these locally in VSCode
if you install an extension that supports Mermaid graphs in Markdown,
and then add this to your `settings.json`:

```json
  "files.associations": {
"*.md.snap": "markdown",
  }
