Find the subagents a session spawned

Multi-agent runs delegate work to child sessions. The parent’s status lists their IDs in subagent_session_ids; pass the parent’s ID to parent_session_id to pull the whole roster in one call, each child labeled with the agent that ran it. Walk deeper trees by recursing on a child’s own ID.
