fix: properly handle Python 3.13 support with PyTorch compatibility

- Support Python 3.13 on most platforms (Ubuntu, ARM64 Mac)
- Exclude Intel Mac + Python 3.13 combination due to PyTorch wheel availability
- PyTorch <2.5 supports Intel Mac but not Python 3.13
- PyTorch 2.5+ supports Python 3.13 but not Intel Mac x86_64
- Document limitation in CI configuration comments
- Update README badges with detailed Python version support and CI status
