Method execute

core/src/tools/task.rs:269–278

Execute a task by spawning an isolated child AgentLoop. `parent_session_id` flows into the emitted `SubagentStart`/`SubagentEnd` events so dashboards can associate child runs with the parent session.

        params: TaskParams,

    )

    /// `parent_session_id` flows into the emitted `SubagentStart`/`SubagentEnd`
    /// events so dashboards can associate child runs with the parent session.

    /// so the synchronously-returned task id matches the one in lifecycle events.
