Register the offline-region:// protocol on MapLibre if it is not registered
already. Idempotent per scheme, exactly like the PMTiles registration: several
maps loading the same region concurrently share one registration.
Because MapLibre's protocol table is process-global, the first handler wins
for a given scheme. A host that needs to serve a different region on the same
scheme must resetOfflineRegionProtocol first, or register the second
region under its own scheme.
