Use Tokens from parsed type annotation or parsed source (#11740)
## Summary

This PR fixes a bug where the checker would require the tokens for an
invalid offset w.r.t. the source code.

Taking the source code from the linked issue as an example:
```py
relese_version :"0.0is 64"
```

Now, this isn't really a valid type annotation but that's what this PR
is fixing. Regardless of whether it's valid or not, Ruff shouldn't
panic.

The checker would visit the parsed type annotation (`0.0is 64`) and try
to detect any violations. Certain rule logic requests the tokens for the
same but it would fail because the lexer would only have the `String`
token considering original source code. This worked before because the
lexer was invoked again for each rule logic.

The solution is to store the parsed type annotation on the checker if
it's in a typing context and use the tokens from that instead if it's
available. This is enforced by creating a new API on the checker to get
the tokens.

But, this means that there are two ways to get the tokens via the
checker API. I want to restrict this in a follow-up PR (#11741) to only
expose `tokens` and `comment_ranges` as methods and restrict access to
the parsed source code.

fixes: #11736 

## Test Plan

- [x] Add a test case for `F632` rule and update the snapshot
- [x] Check all affected rules
- [x] No ecosystem changes

Update NPY001 rule for NumPy 2.0 (#11735)
Hi!

This PR addresses https://github.com/astral-sh/ruff/issues/11093.

It skips `np.bool` and `np.long` replacements as both of these names
were reintroduced in NumPy 2.0 with a different meaning
(https://github.com/numpy/numpy/pull/24922,
https://github.com/numpy/numpy/pull/25080).
With this change `NPY001` will no longer conflict with `NPY201`. For
projects using NumPy 1.x `np.bool` and `np.long` has been deprecated and
removed long time ago, and accessing them yields an informative error
message.

Respect per-file ignores for blanket and redirected noqa rules (#11728)
## Summary

Ensures that we respect per-file ignores and exemptions for these rules.
Specifically, we allow:

```python
# ruff: noqa: PGH004
```

...to ignore `PGH004`.

[pygrep_hooks] Check blanket ignores via file-level pragmas (PGH004) (#11540)
## Summary

Should resolve https://github.com/astral-sh/ruff/issues/11454.

This is my first PR to `ruff`, so I may have missed something.

If I understood the suggestion in the issue correctly, rule `PGH004`
should be set to `Preview` again.

## Test Plan

Created two fixtures derived from the issue.

[flake8-bugbear] Implement return-in-generator (B901) (#11644)
## Summary

This PR implements the rule B901, which is part of the opinionated rules
of `flake8-bugbear`.

This rule seems to be desired in `ruff` as per
https://github.com/astral-sh/ruff/issues/3758 and
https://github.com/astral-sh/ruff/issues/2954#issuecomment-1441162976.

## Test Plan

As this PR was made closely following the
[CONTRIBUTING.md](8a25531a71/CONTRIBUTING.md),
it tests using the snapshot approach, that is described there.

## Sources

The implementation is inspired by [the original implementation in the
`flake8-bugbear`
repository](d1aec4cbef/bugbear.py (L1092)).
The error message and [test
file](d1aec4cbef/tests/b901.py)
where also copied from there.

The documentation I came up with on my own and needs improvement. Maybe
the example given in
https://github.com/astral-sh/ruff/issues/2954#issuecomment-1441162976
could be used, but maybe they are too complex, I'm not sure.

## Open Questions

- [ ] Documentation. (See above.)

- [x] Can I access the parent in a visitor?

The [original
implementation](d1aec4cbef/bugbear.py (L1100))
references the `yield` statement's parent to check if it is an
expression statement. I didn't find a way to do this in `ruff` and used
the `is_expresssion_statement` field on the visitor instead. What are
your thoughts on this? Is it possible and / or desired to access the
parent node here?

- [x] Is `Option::is_some(...)` -> `...unwrap()` the right thing to do?

Referring to [this piece of
code](9d5a280f71/crates/ruff_linter/src/rules/flake8_bugbear/rules/return_x_in_generator.rs (L91-L96)).
From my understanding, the `.unwrap()` is safe, because it is checked
that `return_` is not `None`. However, I feel like I missed a more
elegant solution that does both in one.

## Other

I don't know a lot about this rule, I just implemented it because I
found it in a
https://github.com/astral-sh/ruff/labels/good%20first%20issue.

I'm new to Rust, so any constructive critisism is appreciated.

Infer indentation with imports when logical indent is absent (#11608)
## Summary

In an `__init__.py` file, it's not uncommon to lack a logical indent
(since it may just contain imports). In such cases, we were always
falling back to four-space indent. This PR adds detection for indents
within import groups.

[flake8-async] Sleep with >24 hour interval should usually sleep forever (ASYNC116) (#11498)
## Summary

Addresses #8451 by implementing rule 116 to add an unsafe fix when sleep
is used with a >24 hour interval to instead consider sleeping forever.

This rule is added as async instead as I my understanding was that these
trio rules would be moved to async anyway.

There are a couple of TODOs, which address further extending the rule by
adding support for lookups and evaluations, and also supporting `anyio`.

Mark quotes as unnecessary for non-evaluated annotations (#11485)
## Summary

Similar to #11414, this PR extends `UP037` to flag quoted annotations
that are located in positions that won't be evaluated at runtime.

For example, the quotes on `Tuple` are unnecessary in:

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from typing import Tuple


def foo():
    x: "Tuple[int, int]" = (0, 0)

foo()

F401 - Recommend adding unused import bindings to __all__ (#11314)
Followup on #11168 and resolve #10391

# User facing changes

* F401 now recommends a fix to add unused import bindings to to
`__all__` if a single `__all__` list or tuple is found in `__init__.py`.
* If there are no `__all__` found in the file, fall back to recommending
redundant-aliases.
* If there are multiple `__all__` or only one but of the wrong type (non
list or tuple) then diagnostics are generated without fixes.
* `fix_title` is updated to reflect what the fix/recommendation is.

Subtlety: For a renamed import such as `import foo as bees`, we can
generate a fix to add `bees` to `__all__` but cannot generate a fix to
produce a redundant import (because that would break uses of the binding
`bees`).

# Implementation changes

* Add `name` field to `ImportBinding` to contain the name of the
_binding_ we want to add to `__all__` (important for the `import foo as
bees` case). It previously only contained the `AnyImport` which can give
us information about the import but not the binding.
* Add `binding` field to `UnusedImport` to contain the same. (Naming
note: the field `name` field already existed on `UnusedImport` and
contains the qualified name of the imported symbol/module)
* Change `fix_by_reexporting` to branch on the size of `dunder_all:
Vec<&Expr>`
* For length 0 call the edit-producing function `make_redundant_alias`.
  * For length 1 call edit-producing function `add_to_dunder_all`.
  * Otherwise, produce no fix.
* Implement the edit-producing function `add_to_dunder_all` and add unit
tests.
* Implement several fixture tests: empty `__all__ = []`, nonempty
`__all__ = ["foo"]`, mis-typed `__all__ = None`, plus-eq `__all__ +=
["foo"]`
* `UnusedImportContext::Init` variant now has two fields: whether the
fix is in `__init__.py` and how many `__all__` were found.

# Other changes

* Remove a spurious pattern match and instead use field lookups b/c the
addition of a field would have required changing the unrelated pattern.
* Tweak input type of `make_redundant_alias`

F401 - Distinguish between imports we wish to remove and those we wish to make explicit-exports (#11168)
Resolves #10390 and starts to address #10391

# Changes to behavior

* In `__init__.py` we now offer some fixes for unused imports.
* If the import binding is first-party this PR suggests a fix to turn it
into a redundant alias.
* If the import binding is not first-party, this PR suggests a fix to
remove it from the `__init__.py`.
* The fix-titles are specific to these new suggested fixes.
* `checker.settings.ignore_init_module_imports` setting is
deprecated/ignored. There is probably a documentation change to make
that complete which I haven't done.

---

<details><summary>Old description of implementation changes</summary>

# Changes to the implementation

* In the body of the loop over import statements that contain unused
bindings, the bindings are partitioned into `to_reexport` and
`to_remove` (according to how we want to resolve the fact they're
unused) with the following predicate:
  ```rust
in_init && is_first_party(checker, &import.qualified_name().to_string())
// true means make it a reexport
  ```
* Instead of generating a single fix per import statement, we now
generate up to two fixes per import statement:
  ```rust
  (fix_by_removing_imports(checker, node_id, &to_remove, in_init).ok(),
   fix_by_reexporting(checker, node_id, &to_reexport, dunder_all).ok())
  ```
* The `to_remove` fixes are unsafe when `in_init`.
* The `to_explicit` fixes are safe. Currently, until a future PR, we
make them redundant aliases (e.g. `import a` would become `import a as
a`).

## Other changes

* `checker.settings.ignore_init_module_imports` is deprecated/ignored.
Instead, all fixes are gated on `checker.settings.preview.is_enabled()`.
* Got rid of the pattern match on the import-binding bound by the inner
loop because it seemed less readable than referencing fields on the
binding.
* [x] `// FIXME: rename "imports" to "bindings"` if reviewer agrees (see
code)
* [x] `// FIXME: rename "node_id" to "import_statement"` if reviewer
agrees (see code)

<details>
<summary><h2>Scope cut until a future PR</h2></summary>

* (Not implemented) The `to_explicit` fixes will be added to `__all__`
unless it doesn't exist. When `__all__` doesn't exist they're resolved
by converting to redundant aliases (e.g. `import a` would become `import
a as a`).
 
---

</details>

# Test plan

* [x] `crates/ruff_linter/resources/test/fixtures/pyflakes/F401_24`
contains an `__init__.py` with*out* `__all__` that exercises the
features in this PR, but it doesn't pass.
* [x]
`crates/ruff_linter/resources/test/fixtures/pyflakes/F401_25_dunder_all`
contains an `__init__.py` *with* `__all__` that exercises the features
in this PR, but it doesn't pass.
* [x] Write unit tests for the new edit functions in
`fix::edits::make_redundant_alias`.

Avoid debug assertion around NFKC renames (#11249)
## Summary

This assertion isn't quite correct, since with NFKC normalization, two
identifiers can have different lengths but map to the same binding.

Closes https://github.com/astral-sh/ruff/issues/11238.

Ignore non-abstract class attributes when enforcing B024 (#11210)
## Summary

I think the check included here does make sense, but I don't see why we
would allow it if a value is provided for the attribute -- since, in
that case, isn't it _not_ abstract?

Closes: https://github.com/astral-sh/ruff/issues/11208.
