The old setuptools-based build system has been fully replaced with
scikit-build-core. Renaming setup.py to deprecated_setup.py to:
- Clearly indicate it's no longer the primary build method
- Keep it available for reference and backward compatibility
- Prevent accidental use of the old build system
Users should now use: pip install .
