Note

Centralize submission readiness path into a constant in test metadata

Replaces hardcoded "docs/SUBMISSION_READINESS.md" strings in tests/test_metadata.py with a single SUBMISSION_READINESS_PATH constant, used in both EXPECTED_SUBMISSION_READINESS_LINK and the per-surface assertion in test_release_metadata_surfaces_stay_aligned.
