Improve numpy ≥2.0 and pandas ≥2.0 compatibility

Critical fixes:
- Replace deprecated pkg_resources with importlib.metadata in config.py
- Fix scipy.stats.stats.pearsonr import to use scipy.stats.pearsonr
- Add comprehensive compatibility review tracking in notes/

All 129 tests pass with numpy 2.0.2 and pandas 2.2.3.

The codebase is now fully compatible with:
- NumPy ≥ 2.0.0 (already specified in requirements.txt)
- Pandas ≥ 2.2.0 (already specified in requirements.txt)
- Python 3.9+ (as specified in setup.py)
