Method with_subagent_tracker

core/src/tools/task.rs:257–263

Share a tracker with this executor. When set, each task registers a `CancellationToken` against the tracker so the parent session can cancel by `task_id`.

        mut self,
        tracker: Arc<crate::subagent_task_tracker::InMemorySubagentTaskTracker>,

    /// a `CancellationToken` against the tracker so the parent session
    /// can cancel by `task_id`.
