Command backfill-canonical-user-ids rewrites legacy Auth0-subject values in the *_meta and *_versions audit fields (created_by, updated_by, submitted_by, reviewed_by) to the canonical users._id each subject maps to, using users-api's internal resolve-subjects batch endpoint.

Command backfill-volume-system-titles populates the denormalized system_titles map on every existing volume by resolving each referenced game system's current title from game-systems-api once.

Command consumer runs the system-title sync JetStream consumer as a standalone process, for local development without the full catalog-api server.
