Add ARM64 support and enable workflows on feature branch

- Add ARM64 testing for Linux (ubuntu-latest-arm) and macOS (macos-latest-xlarge)
- Use reduced Python version matrix for ARM64 (3.11, 3.12) to optimize CI time
- Update cache keys to include architecture for proper isolation
- Enable workflows on improve-github-actions branch for testing
- ARM64 runners provide better coverage for Apple Silicon and ARM64 servers
