Bootstrap Python venv with uv when system packages are missing
If python3-dev/pybind11-dev aren't installed and uv is available,
automatically create a local venv at build/pyvenv/ with Python 3.13
and pybind11. Also detects pybind11 cmake dir dynamically instead of
hardcoding the Python version in the path.
