python-cattrs/support-python-3.13.patch
Steve Kowalik 44b2c79ae8 - Update to 25.3.0:
* Potentially breaking: Abstract sets are now structured into frozensets.
  * Python 3.14 is now supported and part of the test matrix.
  * Fix unstructuring NewTypes with the {class}BaseConverter.
  * Make some Hypothesis tests more robust.
  * {func}cattrs.strategies.include_subclasses now works with generic parent
    classes and the tagged union strategy.
  * Potentially breaking: Sequences are now structured into tuples.
  * Add a use_alias parameter to cattrs.Converter.
  * The union passthrough strategy now by default accepts ints for unions
    that contain floats but not ints, when configured to be able to handle
    both ints and floats. This more closely matches the current typing
    behavior.
  * Fix unstructuring of generic classes with stringified annotations.
  * The default disambiguation hook factory is now only enabled for
    converters with unstructure_strat=AS_DICT (the default).
  * Switch to uv and just in lieu of PDM, tox and Make.
  * Fixed AttributeError: no attribute '__parameters__' while structuring
    attrs classes that inherit from parametrized generic aliases from
    collections.abc.
  * Potentially breaking: The converters raise StructureHandlerNotFoundError
    more eagerly (on hook creation, instead of on hook use). This helps
    surfacing problems with missing hooks sooner.
  * typing.Self is now supported in attrs classes, dataclasses, TypedDicts
    and the dict NamedTuple factories. See typing.Self for details.
  * PEP 695 type aliases can now be used with
    BaseConverter.register_structure_hook and
    BaseConverter.register_unstructure_hook. Previously, they required the
    use of BaseConverter.register_structure_hook_func.
  * Some defaultdicts are now supported by default, and
