Conversation
Add Python 3.15 to the CI matrices and package metadata: - pyproject.toml: add the 3.15 classifier and bump requires-python to <3.16 - clang builds: add 3.15 and allow-prereleases in setup-python - build_pip: add 3.15 rows and the conda-forge/label/python_rc channel - conda-package(-cf): add 3.15 rows (numpy 2.5) and the python_rc channel The 3.15 release candidate on conda-forge depends on the _python_rc package, which is only published in conda-forge/label/python_rc.

Python 3.15.0 is released and the final builds are on the conda-forge main label without the _python_rc dependency, and setup-python has it as a stable version: - conda workflows: remove the conda-forge/label/python_rc channel - clang builds: remove allow-prereleases from setup-python

This PR adds Python 3.15 across the CI matrices and package metadata.
Note, only the regular (GIL) 3.15 build is added. The free-threaded 3.15t build is left out for now because conda-forge has no NumPy build for it yet.
