Commit 45f3ce8d88 for wordpress.org

commit 45f3ce8d883c87090b59b152aa8d64665f76f51b
Author: jorgefilipecosta <jorgefilipecosta@git.wordpress.org>

    Abilities API: Allow nested namespace ability names (2-4 segments).

    Expand ability name validation from exactly 2 segments (`namespace/ability`) to 2-4 segments, enabling names like `my-plugin/resource/find` and `my-plugin/resource/sub/find`.
    This allows plugins to organize abilities into logical resource groups. The validation regex changes from `/^[a-z0-9-]+\/[a-z0-9-]+$/` to `/^[a-z0-9-]+(?:\/[a-z0-9-]+){1,3}$/`, which accepts the first segment plus 1-3 additional slash-delimited segments.
    Updates the validation regex, error messages, docblocks, and adds corresponding unit and REST API tests.

    Props jorgefilipecosta, justlevine, jorbin.
    Fixes #64596.
