Decide scope: is CantusDB / full-text search integration needed before launch?

Full-text and metadata search (by title, feast, genre, Cantus ID, etc.) requires real Cantus Database records for the Liber Usualis, which is being tracked as a separate, independent project. OMR/pitch-melody search does not require this (confirmed with a DDMAL maintainer).

This issue is to get explicit team sign-off on whether CantusDB integration is a blocking requirement before considering the Liber Usualis "live" on production Cantus Ultimus, or whether OMR/melody search alone is sufficient for an initial launch, with full-text search following later.
