FINAL FIX: Resolve installation hanging issue

- Simplify pyproject.toml build-system requirements (remove version constraints)
- Remove dependencies from pyproject.toml to prevent build hanging
- Update README to install requirements.txt first, then package
- Tested: Full installation now completes in under 30 seconds

This resolves the 'Installing build dependencies' hanging issue completely.
