"#;Expand description
Claude PostToolUse(Task) hook — record a nested subagent→subagent spawn edge.
Fires after a Task/Agent tool call returns; the payload’s top-level agent_id
is the spawner and tool_response.agentId is the child. Only nested spawns
(spawner is itself a subagent) are recorded — a root spawn is already covered
by the SubagentStart hook. Fire-and-forget, fail-open.
