fix(deps): add missing pytest-timeout for CI environments

Added pytest-timeout>=2.1.0 to core and quality-ci features to resolve CI failures:
- CI environments now support pytest --timeout=120 arguments
- All 4/5 failed workflows should now pass with timeout support
- Eliminates "unrecognized arguments: --timeout=120" errors in CI pipeline

This addresses the critical blocker preventing PR #8 from achieving target 80-95% CI success rate.
