PyO3 0.21 only supports Python up to 3.12. Bumping to 0.22 adds Python 3.13 support while maintaining backward compatibility with the existing gil-refs API (no code changes needed). Also bumps maturin build requirement from 0.14 to 1.x to ensure proper Python 3.13 wheel builds, and updates CI actions to latest versions (checkout v4, setup-python v5, upload/download-artifact v4).

The --find-interpreter flag discovers all Python versions on CI runners, including Python 3.14 which PyO3 0.22 doesn't support. Specify explicit interpreter versions (3.10-3.13) to avoid this. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
On Windows, maturin needs the actual Python interpreters installed for each version. Install 3.10-3.13 via setup-python so maturin can find them when building wheels with -i. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
