Fix Python 3.12 CI failure: exclude pytest-vcr to prevent conflict with pytest-recording

- Add constraint-dependencies to exclude pytest-vcr entirely
- Update CI workflow to explicitly uninstall pytest-vcr after sync
- Resolves RuntimeError: pytest-recording is incompatible with pytest-vcr
- All @pytest.mark.vcr decorators continue to work with pytest-recording
- Verified locally that VCR functionality works without conflicts
