fix: completely remove psutil and rapidfuzz dependencies

Address PR feedback from @aaronsteers to fully remove psutil and rapidfuzz
rather than making them optional dependencies. These packages are unused
and were marked as TODO for removal.

Changes:
- Remove psutil and rapidfuzz from optional dependencies
- Remove 'system' extras group (no longer needed)
- Update deptry comments to reflect complete removal
- Keep google-cloud-secret-manager in dev extras as requested
