1 """Add structured_delta column to musehub_commits.
2
3 structured_delta was stored in the dropped commit_meta JSON blob. This migration
4 adds it as a dedicated nullable JSONB column so the symbol indexer can read it
5 back without losing fidelity on historical commits. New pushes write it directly;
6 historical rows remain NULL and fall back to snapshot diffing.
