fix: upgrade to actions v4 and handle manylinux2014 compatibility

- Upgrade all GitHub Actions to v4 (v3 is deprecated)
- Use manual git checkout in manylinux2014 containers to avoid Node.js issues
- Update artifact naming to ensure uniqueness (required by v4)
- Add fail-fast: false to build strategies
- This maintains manylinux2014 compatibility while using latest actions
