POST /v1/deduplicate now returns an object with a deduplicatedEntities list instead of a bare array (breaking)
New POST /v1/detect-duplicates endpoint added for finding duplicates of an entity, and POST /v1/duplicates/dismiss for dismissing a reported duplicate
New endpoints added for managing the uniqueness criteria that decide when two entities count as duplicates: GET/POST /v1/uniqueness-criteria for listing and creating them, and GET/PUT/DELETE /v1/uniqueness-criteria/{schema} for reading, replacing, and removing the criteria of a single schema
