Avoid removing newlines between docstring headers and rST blocks (#11609)
Given:

```python
def func():
    """
    Example:

    .. code-block:: python

        import foo
    """
```

Removing the newline after the `Example:` header breaks Sphinx
rendering.

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.

Closes https://github.com/astral-sh/ruff/issues/11606.

[flake8-pyi] Implement PYI066 (#11541)
## Summary

- Implements `Y066` from `flake8-pyi` as `PYI066`
- Fixes `PYI006` not being raised for `elif` clauses. This would have
conflicted with PYI006's implementation, so decided to do it in the same
PR.

[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:

```python
from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from typing import Tuple


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

foo()
```

Avoid flagging __future__ annotations as required for non-evaluated type annotations (#11414)
## Summary

If an annotation won't be evaluated at runtime, we don't need to flag
`from __future__ import annotations` as required. This applies both to
quoted annotations and annotations outside of runtime-evaluated
positions, like:

```python

    a_list: list[str] | None = []
    a_list.append("hello")
```

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`

Avoid TCH005 for if stmt with elif/else block (#11376)
## Summary

This PR fixes a bug where the auto-fix for `TCH005` would delete the
entire `if` statement.

The fix in this PR is to not consider it a violation if there are any
`elif`/`else` blocks. This also matches the behavior of the original
plugin.

fixes: #11368

[flake8-bugbear] Ignore enum classes in cached-instance-method (B019) (#11312)
## Summary

While I was here, I also updated the rule to use
`function_type::classify` rather than hard-coding `staticmethod` and
friends.

Per Carl:

> Enum instances are already referred to by the class, forming a cycle
that won't get collected until the class itself does. At which point the
`lru_cache` itself would be collected, too.

Respect logged and re-raised expressions in nested statements (#11301)

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`.

[ruff] Implement redirected-noqa (RUF101) (#11052)
## Summary

Based on discussion in #10850.

As it stands today `RUF100` will attempt to replace code redirects with
their target codes even though this is not the "goal" of `RUF100`. This
behavior is confusing and inconsistent, since code redirects which don't
otherwise violate `RUF100` will not be updated. The behavior is also
undocumented. Additionally, users who want to use `RUF100` but do not
want to update redirects have no way to opt out.

This PR explicitly detects redirects with a new rule `RUF101` and
patches `RUF100` to keep original codes in fixes and reporting.

## Test Plan

Added fixture.

[pygrep_hooks] Fix blanket-noqa panic when last line has noqa with no newline (PGH004) (#11108)
## Summary

Resolves #11102

The error stems from these lines

f5c7a62aa6/crates/ruff_linter/src/noqa.rs (L697-L702)
I don't really understand the purpose of incrementing the last index,
but it makes the resulting range invalid for indexing into `contents`.

For now I just detect if the index is too high in `blanket_noqa` and
adjust it if necessary.

## Test Plan

Created fixture from issue example.
