Fix Python 3.14 update_wrapper pickling with lazy annotations

[BioGeek]

Fixes #585.

Python 3.14 adds __annotate__ to functools.WRAPPER_ASSIGNMENTS, so functools.update_wrapper can copy a wrapped callable’s lazy annotation function onto wrapper instances. When the wrapped callable is a method on an annotated ABC, that copied __annotate__ can close over the class dict and reach _abc_impl, causing:

TypeError: cannot pickle '_abc._abc_data' object

This PR detects the specific redundant __annotate__ copied from __wrapped__ and removes it from the object reduction state before pickling.

Changes

• Strip copied __annotate__ from wrapper instance state when it is identical to __wrapped__.__annotate__.
• Add a stdlib-only regression test using abc and functools.update_wrapper.
• Add a changelog entry.

Validation

Tested the original skore==0.11.4 / scikit-learn==1.8.0 reproducer on CPython 3.14.3.
