fix: ensure uv build uses correct Python version in CI

- Add --python python flag to uv build commands
- This ensures wheels are built with the correct Python version (cp313 for Python 3.13, etc)
- Fixes issue where Python 3.13 CI was building cp311 wheels
- Also adds Python version verification before build
