 * Workaround for a Yandex Responses-compatible backend that assigns an mcp_call item
 * a temporary id (prefixed `000_…`) during streaming, then swaps it for a different
 * permanent id in `response.output_item.done`. Without this rewrite, the downstream
 * tool-card lookup misses the existing part and renders a duplicate card. The
 * `output_index` field stays stable across the item's lifecycle, so it serves as the
 * canonical identity used to remap the done event's id back to the first-seen one.
