Regenerate type hint analysis with clean mypy cache

- Clear mypy cache before analysis to get accurate results
- All submodules now show 0 mypy errors (previously showed 9+)
- Confirms 100% function type annotation coverage
- Confirms 88.38% variable type annotation coverage
- The explicit type annotations for nlpo3 are necessary (not redundant) because nlpo3 is dynamically imported and mypy needs them to avoid "returning Any" errors
