When there is a function or class definition at the end of a suite
followed by the beginning of an alternative block, we have to insert a
single empty line between them.
In the if-else-statement example below, we insert an empty line after
the `foo` in the if-block, but none after the else-block `foo`, since in
the latter case the enclosing suite already adds empty lines.
```python
if sys.version_info >= (3, 10):
def foo():
return "new"
else:
def foo():
return "old"
class Bar:
pass
```
To do so, we track whether the current suite is the last one in the
current statement with a new option on the suite kind.

## Summary
This PR updates the server to build the settings index in parallel using
similar logic as `python_files_in_path`.
This should help with https://github.com/astral-sh/ruff/issues/11366 but
ideally we would want to build it lazily.
## Test Plan
`cargo insta test`
## Summary
I don't know that there's more to do here. We could consider not raising
the violation at all for arguments, but that would have some false
negatives and could also be surprising to users.
Closes https://github.com/astral-sh/ruff/issues/12267.
## Summary
Ensures that, e.g., the following is not considered a
redefinition-without-use:
```python
import contextlib
foo = None
with contextlib.suppress(ImportError):
from some_module import foo
```
Closes https://github.com/astral-sh/ruff/issues/12309.
## Summary
Closes https://github.com/astral-sh/ruff/issues/12291.
## Test Plan
```shell
❯ cargo run check ../uv/foo --select INP
/Users/crmarsh/workspace/uv/foo/bar/baz.py:1:1: INP001 File `/Users/crmarsh/workspace/uv/foo/bar/baz.py` is part of an implicit namespace package. Add an `__init__.py`.
Found 1 error.
```
## Summary
I don't fully understand the purpose of this. In #7905, it was just
copied over from the previous non-preview implementation. But it means
that (e.g.) we don't treat `type(self.foo)` as a type -- which is wrong.
Closes https://github.com/astral-sh/ruff/issues/12290.
## Summary
In order to use single quotes with both the ruff linter and the ruff
formatter,
two different rules must be applied. This was not clear to me when
internet searching "configure ruff single quotes" and it eventually
I filed this issue:
https://github.com/astral-sh/ruff/issues/12003
## Summary
Update the name of `ASYNC109` to match
[upstream](https://flake8-async.readthedocs.io/en/latest/rules.html).
Also update to the functionality to match upstream by supporting
additional context managers from `asyncio` and `anyio`. This doesn't
change any of the detection functionality, but recommends additional
context managers from `asyncio` and `anyio` depending on context.
Part of https://github.com/astral-sh/ruff/issues/12039.
## Test Plan
Added fixture for asyncio recommendation
