Get connector status (the error-bearing read)
GET/usm/v1/connect-clusters/:connect_cluster_id/connectors/:connector_name/status
Native core fields (connector, tasks[], plain trace) plus Cloud extensions. Because execution happens out-of-band from the write call, this is where runtime errors, deferred config-validation failures, and failed-management-operation errors all surface (never as HTTP errors on the accepting call). By default a DELETING connector 404s; pass ?show_deleted=true to read its status and the deletion error in cloud_error while it exists.
