When Qwen returns an unresolved `[(tab_container_N)]` placeholder in multiLoadIframe/barIframe content, treat it as an incomplete response: fall back to a resolved sibling field when available, otherwise return status `unknown` with a `qwen_incomplete_response` error so the record is retried on a later collection pass instead of persisting garbage.
