-- GLM-5.2 is a text-only foundation model. The official model page lists text
-- as both its input and output modality; vision belongs to the separate GLM-5V
-- family. Keep the base catalog, snapshots, and already-created platform rows
-- authoritative so stale/customized image_analysis metadata cannot leak back
-- into model discovery.
