## Summary
This PR updates the fix generation logic for auto-quoting an annotation
to generate an edit even when there's a quote character present.
The logic uses the visitor pattern, maintaining it's state on where it
is and generating the string value one node at a time. This can be
considered as a specialized form of `Generator`. The state required to
maintain is whether we're currently inside a `typing.Literal` or
`typing.Annotated` because the string value in those types should not be
un-quoted i.e., `Generic[Literal["int"]]` should become
`"Generic[Literal['int']]`, the quotes inside the `Literal` should be
preserved.

## Test Plan
Add various test cases to validate this change, validate the snapshots.
There are no ecosystem changes to go through.

## Summary
This pull request resolves some rule thrashing identified in #12427 by
allowing for unused arguments when using `NotImplementedError` with a
variable per [this
comment](https://github.com/astral-sh/ruff/issues/12427#issuecomment-2384727468).
**Note**
This feels a little heavy-handed / edge-case-prone. So, to be clear, I'm
happy to scrap this code and just update the docs to communicate that
`abstractmethod` and friends should be used in this scenario (or
similar). Just let me know what you'd like done!
fixes: #12427
## Test Plan
I added a test-case to the existing `ARG.py` file and ran...
```sh
cargo run -p ruff -- check crates/ruff_linter/resources/test/fixtures/flake8_unused_arguments/ARG.py --no-cache --preview --select ARG002
```

## Summary
Treat async generators as "await" in ASYNC100.
Fixes#13637
## Test Plan
Updated snapshot
## Summary
Resolves https://github.com/astral-sh/ruff/issues/9962 by allowing a
configuration setting `allowed-unused-imports`
TODO:
- [x] Figure out the correct name and place for the setting; currently,
I have added it top level.
- [x] The comparison is pretty naive. I tried using `glob::Pattern` but
couldn't get it to work in the configuration.
- [x] Add tests
- [x] Update documentations
## Test Plan
`cargo test`
Closes https://github.com/astral-sh/ruff/issues/13545
As described in the issue, we move comments before the inner `if`
statement to before the newly constructed `elif` statement (previously
`else`).
## Summary
fix#13602
Currently, `UP043` only applies to typing.Generator, but it should also
support collections.abc.Generator.
This update ensures `UP043` correctly handles both
`collections.abc.Generator` and `collections.abc.AsyncGenerator`
### UP043
> `UP043`
> Python 3.13 introduced the ability for type parameters to specify
default values. As such, the default type arguments for some types in
the standard library (e.g., Generator, AsyncGenerator) are now optional.
> Omitting type parameters that match the default values can make the
code more concise and easier to read.
```py
Generator[int, None, None] -> Generator[int]
```

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.
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
The `SequenceIndexVisitor` currently does not recurse into
subexpressions of subscripts when searching for subscript accesses that
would trigger this rule. That means that we don't currently detect
violations of the rule on snippets like this:
```py
data = {"a": 1, "b": 2}
column_names = ["a", "b"]
for index, column_name in enumerate(column_names):
_ = data[column_names[index]]
```
Fixes#13183
