## Summary
Resolves#15695, rework of #15704.
This change modifies the Mdtests framework so that:
* Paths must now be specified in a separate preceding line:
`````markdown
`a.py`:
```py
x = 1
```
`````
If the path of a file conflicts with its `lang`, an error will be
thrown.
* Configs are no longer accepted. The pattern still take them into
account, however, to avoid "Unterminated code block" errors.
* Unnamed files are now assigned unique, `lang`-respecting paths
automatically.
Additionally, all legacy usages have been updated.
## Test Plan
Unit tests and Markdown tests.

This extracts some pure refactoring noise from
https://github.com/astral-sh/ruff/pull/15861. This changes the API for
creating and evaluating visibility constraints, but does not change how
they are respresented internally. There should be no behavioral or
performance changes in this PR.
Changes:
- Hide the internal representation isn't changed, so that we can make
changes to it in #15861.
- Add a separate builder type for visibility constraints. (With TDDs, we
will have some additional builder state that we can throw away once
we're done constructing.)
- Remove a layer of helper methods from `UseDefMapBuilder`, making
`SemanticIndexBuilder` responsible for constructing whatever visibility
constraints it needs.
## Summary
Add support for implicitly-defined instance attributes, i.e. support
type inference for cases like this:
```py
class C:
def __init__(self) -> None:
self.x: int = 1
self.y = None
reveal_type(C().x) # int
reveal_type(C().y) # Unknown | None
```
## Benchmarks
Codspeed reports no change in a cold-cache benchmark, and a -1%
regression in the incremental benchmark. On `black`'s `src` folder, I
don't see a statistically significant difference between the branches:
| Command | Mean [ms] | Min [ms] | Max [ms] | Relative |
|:---|---:|---:|---:|---:|
| `./red_knot_main check --project /home/shark/black/src` | 133.7 ± 9.5 | 126.7 | 164.7 | 1.01 ± 0.08 |
| `./red_knot_feature check --project /home/shark/black/src` | 132.2 ± 5.1 | 118.1 | 140.9 | 1.00 |
## Test Plan
Updated and new Markdown tests
## Summary
Given the following code:
```python
set(([x for x in range(5)]))
```
the current implementation of C403 results in
```python
{(x for x in range(5))}
```
which is a set containing a generator rather than the result of the
generator.
This change removes the extraneous parentheses so that the resulting
code is:
```python
{x for x in range(5)}
```
## Test Plan
`cargo nextest run` and `cargo insta test`
## Summary
Related to #15848, this PR adds the imports explicitly as we'll now flag
these symbols as undefined.

This change does a simple swap of the existing renderer for one that
uses our vendored copy of `annotate-snippets`. We don't change anything
about the diagnostic data model, but this alone already makes
diagnostics look a lot nicer!
This mimics a simplification we have on the OR side, where we simplify
`A ∨ !A` to true. This requires changes to how we add `while` statements
to the semantic index, since we now need distinct
`VisibilityConstraint`s if we need to model evaluating a `Constraint`
multiple times at different points in the execution of the program.
Something Alex and I threw together during our 1:1 this morning. Allows
us to collect statistics on the prevalence of various types in a file,
most usefully TODO types or other dynamic types.
## Summary
This is a follow-up to #15565, tracked in #15642, to reuse the string
replacement logic from the other PEP 695 rules instead of the
`Generator`, which has the benefit of preserving more comments. However,
comments in some places are still dropped, so I added a check for this
and update the fix safety accordingly. I also added a `## Fix safety`
section to the docs to reflect this and the existing `isinstance`
caveat.
## Test Plan
Existing UP040 tests, plus some new cases.
## Summary
Resolves#10063 and follow-up to #15521.
The fix is now marked as unsafe if there are any comments within its
range. Tests are adapted from that of #15521.
## Test Plan
`cargo nextest run` and `cargo insta test`.
Both `list` and `dict` expect only a single positional argument. Giving
more positional arguments, or a keyword argument, is a `TypeError` and
neither the lint rule nor its fix make sense in that context.
Closes#15810
## Summary
Fixes https://github.com/astral-sh/ruff/issues/15812 by visiting the
second argument as a type definition.
## Test Plan
New F401 tests based on the report.

Builtin bindings are given a range of `0..0`, which causes strange
behavior when range checks are made at the top of the file. In this
case, the logic of the rule demands that the value of the dict
comprehension is not self-referential (i.e. it does not contain
definitions for any of the variables used within it). This logic was
confused by builtins which looked like they were defined "in the
comprehension", if the comprehension appeared at the top of the file.
Closes#15830
## Summary
This PR removes a trailing semicolon after an interface definition in
the custom TypeScript section of `ruff_wasm`. Currently, this semicolon
triggers the error "TS1036: Statements are not allowed in ambient
contexts" when including the file and compiling with e.g `tsc`.
## Test Plan
I made the change, ran `wasm-pack` and copied the generated directory
manually to my `node_modules` folder. I then compiled a file importing
`@astral-sh/ruff-wasm-web` again and confirmed that the compilation
error was gone.
If there is any `ParenthesizedWhitespace` (in the sense of LibCST) after
the function name `sorted` and before the arguments, then we must wrap
`sorted` with parentheses after removing the surrounding function.
Closes#15789
This PR uses the tokens of the parsed annotation available in the
`Checker`, instead of re-lexing (using `SimpleTokenizer`) the
annotation. This avoids some limitations of the `SimpleTokenizer`, such
as not being able to handle number and string literals.
Closes#15816 .
## Summary
Permits suspicious imports (the `S4` namespaced diagnostics) from stub
files.
Closes#15207.
## Test Plan
Added tests and ran `cargo nextest run`. The test files are copied from
the `.py` variants.
