chore: full typing cleanup, paper references update, and contributors file for JOSS submission

- Fix isolated build issue with openai-whisper via setuptools pinning in pyproject.toml

- Complete mypy strict typing fixes across entire src/ directory

- Ensure 100% test coverage and zero test failures

- Add missing JOSS paper citations (DeepFace, LAION, ByteTrack) and update test counts

- Add complete CONTRIBUTORS.md per JOSS guidelines
