Fix compatibility test versions for NumPy 2.0 support

- Update Python 3.9 test to use scikit-learn 1.3.2 (fixes ComplexWarning import error)
- Update Python 3.12 test to use scikit-learn 1.7.2 (proper NumPy 2.0 support)
- Fix NumPy constraint installation to ensure correct versions
- Simplify compatibility test matrix to focus on critical combinations
- Update version to 0.1.2.post12
- Remove auto-generated requirements.txt (project uses pyproject.toml)

Both compatibility tests now pass:
- Python 3.9 + scikit-learn 1.3.2 + NumPy 1.26.4 ✅
- Python 3.12 + scikit-learn 1.7.2 + NumPy 2.0.2 ✅
