Download an Aria model bundle. By default the server returns a 302 redirect to a short-lived S3 presigned URL. For directory-keyed bundles it streams a ZIP file. Request Accept: application/json or add ?format=json to receive the URL as JSON instead. Method: GET Path: /api/models/{slug}/download Auth: Session Bearer, ?token= query JWT, or Bearer API key (bfvk-...)
