fix(ci): exclude slow integration tests from CI pipeline

- Add @pytest.mark.integration and @pytest.mark.slow to responsiveness tests
- Update CI workflows to exclude slow and integration tests
- Reduces CI test count from 165 to 150 tests (15 deselected)
- Focuses CI on fast unit and medium integration tests

Improves CI reliability by excluding flaky performance tests
