debug: add comprehensive CI debugging for pytest collection failure

- Add environment checks to CI workflow
- Test package imports directly
- Add pytest collection dry run with continue-on-error
- Simplify pytest.ini to absolute minimum
- Add basic test that doesn't import our package
- This will help us understand why pytest fails with exit code 2
