This PR updates typing-extensions from 4.8.0 to 4.12.2.

Changelog

4.12.2

- Fix regression in v4.12.0 where specialization of certain
generics with an overridden `__eq__` method would raise errors.
Patch by Jelle Zijlstra.
- Fix tests so they pass on 3.13.0b2

4.12.1

- Preliminary changes for compatibility with the draft implementation
of PEP 649 in Python 3.14. Patch by Jelle Zijlstra.
- Fix regression in v4.12.0 where nested `Annotated` types would cause
`TypeError` to be raised if the nested `Annotated` type had unhashable
metadata. Patch by Alex Waygood.

4.12.0

This release is mostly the same as 4.12.0rc1 but fixes one more
longstanding bug.

- Fix incorrect behaviour of `typing_extensions.ParamSpec` on Python 3.8 and
3.9 that meant that
`isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar)` would have a
different result in some situations depending on whether or not a profiling
function had been set using `sys.setprofile`. Patch by Alex Waygood.

4.12.0rc1

This release focuses on compatibility with the upcoming release of
Python 3.13. Most changes are related to the implementation of type
parameter defaults (PEP 696).

Thanks to all of the people who contributed patches, especially Alex
Waygood, who did most of the work adapting typing-extensions to the
CPython PEP 696 implementation.

Full changelog:

- Improve the implementation of type parameter defaults (PEP 696)
- Backport the `typing.NoDefault` sentinel object from Python 3.13.
 TypeVars, ParamSpecs and TypeVarTuples without default values now have
 their `__default__` attribute set to this sentinel value.
- TypeVars, ParamSpecs and TypeVarTuples now have a `has_default()`
 method, matching `typing.TypeVar`, `typing.ParamSpec` and
 `typing.TypeVarTuple` on Python 3.13+.
- TypeVars, ParamSpecs and TypeVarTuples with `default=None` passed to
 their constructors now have their `__default__` attribute set to `None`
 at runtime rather than `types.NoneType`.
- Fix most tests for `TypeVar`, `ParamSpec` and `TypeVarTuple` on Python
 3.13.0b1 and newer.
- Backport CPython PR [118774](https://github.com/python/cpython/pull/118774),
 allowing type parameters without default values to follow those with
 default values in some type parameter lists. Patch by Alex Waygood,
 backporting a CPython PR by Jelle Zijlstra.
- It is now disallowed to use a `TypeVar` with a default value after a
 `TypeVarTuple` in a type parameter list. This matches the CPython
 implementation of PEP 696 on Python 3.13+.
- Fix bug in PEP-696 implementation where a default value for a `ParamSpec`
 would be cast to a tuple if a list was provided.
 Patch by Alex Waygood.
- Fix `Protocol` tests on Python 3.13.0a6 and newer. 3.13.0a6 adds a new
`__static_attributes__` attribute to all classes in Python,
which broke some assumptions made by the implementation of
`typing_extensions.Protocol`. Similarly, 3.13.0b1 adds the new
`__firstlineno__` attribute to all classes.
- Fix `AttributeError` when using `typing_extensions.runtime_checkable`
in combination with `typing.Protocol` on Python 3.12.2 or newer.
Patch by Alex Waygood.
- At runtime, `assert_never` now includes the repr of the argument
in the `AssertionError`. Patch by Hashem, backporting of the original
fix https://github.com/python/cpython/pull/91720 by Jelle Zijlstra.
- The second and third parameters of `typing_extensions.Generator`,
and the second parameter of `typing_extensions.AsyncGenerator`,
now default to `None`. This matches the behaviour of `typing.Generator`
and `typing.AsyncGenerator` on Python 3.13+.
- `typing_extensions.ContextManager` and
`typing_extensions.AsyncContextManager` now have an optional second
parameter, which defaults to `Optional[bool]`. The new parameter
signifies the return type of the `__(a)exit__` method, matching
`typing.ContextManager` and `typing.AsyncContextManager` on Python
3.13+.
- Backport `types.CapsuleType` from Python 3.13.
- Releases are now made using [Trusted Publishers](https://docs.pypi.org/trusted-publishers/)
improving the security of the release process. Patch by Jelle Zijlstra.

4.12.0a1

These releases primarily test a revised release workflow. If all goes
well, release 4.12.0rc1 will follow soon.

4.11.0

This feature release provides improvements to various recently
added features, most importantly type parameter defaults (PEP 696).

There are no changes since 4.11.0rc1.

4.11.0rc1

- Fix tests on Python 3.13.0a5. Patch by Jelle Zijlstra.
- Fix the runtime behavior of type parameters with defaults (PEP 696).
Patch by Nadir Chowdhury.
- Fix minor discrepancy between error messages produced by `typing`
and `typing_extensions` on Python 3.10. Patch by Jelle Zijlstra.
- When `include_extra=False`, `get_type_hints()` now strips `ReadOnly` from the annotation.

4.10.0

This feature release adds support for PEP 728 (TypedDict with extra
items) and PEP 742 (``TypeIs``).

There are no changes since 4.10.0rc1.

4.10.0rc1

- Add support for PEP 728, supporting the `closed` keyword argument and the
special `__extra_items__` key for TypedDict. Patch by Zixuan James Li.
- Add support for PEP 742, adding `typing_extensions.TypeIs`. Patch
by Jelle Zijlstra.
- Drop runtime error when a read-only `TypedDict` item overrides a mutable
one. Type checkers should still flag this as an error. Patch by Jelle
Zijlstra.
- Speedup `issubclass()` checks against simple runtime-checkable protocols by
around 6% (backporting https://github.com/python/cpython/pull/112717, by Alex
Waygood).
- Fix a regression in the implementation of protocols where `typing.Protocol`
classes that were not marked as `runtime_checkable` would be unnecessarily
introspected, potentially causing exceptions to be raised if the protocol had
problematic members. Patch by Alex Waygood, backporting
https://github.com/python/cpython/pull/113401.

4.9.0

This feature release adds `typing_extensions.ReadOnly`, as specified
by PEP 705, and makes various other improvements, especially to
`typing_extensions.deprecated()`.

There are no changes since 4.9.0rc1.

4.9.0rc1

- Add support for PEP 705, adding `typing_extensions.ReadOnly`. Patch
by Jelle Zijlstra.
- All parameters on `NewType.__call__` are now positional-only. This means that
the signature of `typing_extensions.NewType.__call__` now exactly matches the
signature of `typing.NewType.__call__`. Patch by Alex Waygood.
- Fix bug with using `deprecated` on a mixin class. Inheriting from a
deprecated class now raises a `DeprecationWarning`. Patch by Jelle Zijlstra.
- `deprecated` now gives a better error message if you pass a non-`str`
argument to the `msg` parameter. Patch by Alex Waygood.
- `deprecated` is now implemented as a class for better introspectability.
Patch by Jelle Zijlstra.
- Exclude `__match_args__` from `Protocol` members.
Backport of https://github.com/python/cpython/pull/110683 by Nikita Sobolev.
- When creating a `typing_extensions.NamedTuple` class, ensure `__set_name__`
is called on all objects that define `__set_name__` and exist in the values
of the `NamedTuple` class's class dictionary. Patch by Alex Waygood,
backporting https://github.com/python/cpython/pull/111876.
- Improve the error message when trying to call `issubclass()` against a
`Protocol` that has non-method members. Patch by Alex Waygood (backporting
https://github.com/python/cpython/pull/112344, by Randolph Scholz).
