## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
There was a typo in the links of the docs of PTH116, where Path.stat
used to link to Path.group.
Another rule, PTH202, does it correctly:
ec72e675d9/crates/ruff_linter/src/rules/flake8_use_pathlib/rules/os_path_getsize.rs (L33)
This PR only fixes a one word typo.
## Test Plan
<!-- How was it tested? -->
I did not test that the doc generation framework picked up these
changes, I assume it will do it successfully.
## Summary
Following #13449, this PR adds custom handling for the bool constructor,
so when the input type has statically known truthiness value, it will be
used as the return value of the bool function.
For example, in the following snippet x will now be resolved to
`Literal[True]` instead of `bool`.
```python
x = bool(1)
```
## Test Plan
Some cargo tests were added.

## Summary
Implement inference for `f-string`, contributes to #12701.
### First Implementation
When looking at the way `mypy` handles things, I noticed the following:
- No variables (e.g. `f"hello"`) ⇒ `LiteralString`
- Any variable (e.g. `f"number {1}"`) ⇒ `str`
My first commit (1ba5d0f13fdf70ed8b2b1a41433b32fc9085add2) implements
exactly this logic, except that we deal with string literals just like
`infer_string_literal_expression` (if below `MAX_STRING_LITERAL_SIZE`,
show `Literal["exact string"]`)
### Second Implementation
My second commit (90326ce9af5549af7b4efae89cd074ddf68ada14) pushes
things a bit further to handle cases where the expression within the
`f-string` are all literal values (string representation known at static
time).
Here's an example of when this could happen in code:
```python
BASE_URL = "https://httpbin.org"
VERSION = "v1"
endpoint = f"{BASE_URL}/{VERSION}/post" # Literal["https://httpbin.org/v1/post"]
```
As this can be sightly more costly (additional allocations), I don't
know if we want this feature.
## Test Plan
- Added a test `fstring_expression` covering all cases I can think of

Doesn't offer a valid fix, opting to instead just not offer a fix at
all. If someone points me to a good way to handle parenthesis here I'm
down to try to fix the fix separately, but it looks quite hard.

Building ruff on AIX breaks on `tiki-jemalloc-sys` due to OS header
incompatibility
## Test Plan
`cargo test`

In https://github.com/astral-sh/ruff/pull/13503, we added supported for
detecting variadic keyword arguments as dictionaries, here we use the
same strategy for detecting variadic positional arguments as tuples.
Closes https://github.com/astral-sh/ruff/issues/13266
Avoids false negatives for shadowed bindings that aren't actually
references to the loop variable. There are some shadowed bindings we
need to support still, e.g., `del` requires the loop variable to exist.
## Summary
I think we should also make the change that @BurntSushi recommended in
the linked issue, but this gets rid of the panic.

## Summary
This PR changes removes the typeshed stubs from the vendored file system
shipped with ruff
and instead ships an empty "typeshed".
Making the typeshed files optional required extracting the typshed files
into a new `ruff_vendored` crate. I do like this even if all our builds
always include typeshed because it means `red_knot_python_semantic`
contains less code that needs compiling.
This also allows us to use deflate because the compression algorithm
doesn't matter for an archive containing a single, empty file.
## Test Plan
`cargo test`
I verified with ` cargo tree -f "{p} {f}" -p <package> ` that:
* red_knot_wasm: enables `deflate` compression
* red_knot: enables `zstd` compression
* `ruff`: uses stored
I'm not quiet sure how to build the binary that maturin builds but
comparing the release artifact size with `strip = true` shows a `1.5MB`
size reduction

## Summary
For reasons I haven't investigated, this speeds up the resolver about 2x
(from 6.404s to 3.612s on an extremely large codebase).

Where that's `main`, then (`ruff-patch`) using the version with no
`File`, no `SemanticModel`, then (`ruff-patch2`) using `File`.
Avoid quadratic time in subsumed elements when adding a super-type of
existing union elements.
Reserve space in advance when adding multiple elements (from another
union) to a union.
Make union elements a `Box<[Type]>` instead of an `FxOrderSet`; the set
doesn't buy much since the rules of union uniqueness are defined in
terms of supertype/subtype, not in terms of simple type identity.
Move sealed-boolean handling out of a separate `UnionBuilder::simplify`
method and into `UnionBuilder::add`; now that `add` is iterating
existing elements anyway, this is more efficient.
Remove `UnionType::contains`, since it's now `O(n)` and we shouldn't
really need it, generally we care about subtype/supertype, not type
identity. (Right now it's used for `Type::Unbound`, which shouldn't even
be a type.)
Add support for `is_subtype_of` for the `object` type.
Addresses comments on https://github.com/astral-sh/ruff/pull/13401
This was mentioned in an earlier review, and seemed easy enough to just
do it. No need to repeat all the types twice when it gives no additional
information.
