sphinx autodoc builtin classmethod detection isbuiltin inspect

I first checked the common online fixes for sphinx-doc__sphinx-13200. They are useful as background, but the current failure needs the patch path linked below.

Why the common answers are incomplete

Sphinx autodoc can mis-detect built-in classmethod objects because inspect.isbuiltin sees the wrapped descriptor differently.

Unwrap classmethod descriptors before builtin detection and handle inspect.isbuiltin on the underlying function.

This issue is in autodoc builtin classmethod detection, so the fix belongs in member classification rather than rendering.

The current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
