 * Tool observation returned when the sub-workflow parked in a waiting state (HITL approval,
 * long Wait, webhook/form resume). On the in-process agent paths (v1/v2 `supplyData`) this
 * value goes straight to the LLM while the parent parks, so it must be self-describing: a
 * bare `{}` reads as "the workflow returned nothing", which invites a wrong final answer or
 * a duplicate tool call (spawning a second child execution and approval message). On the v3
 * engine path the model never sees it — the parked run is re-run with the child's real
 * output on resume.
