Method register_canceller

core/src/subagent_task_tracker.rs:113–118

Register a `CancellationToken` for a running task so callers can trigger cancellation through `cancel(task_id)`. The task executor is expected to remove the entry on exit via `clear_canceller`.

(&self, task_id: &str, token: CancellationToken)

    /// trigger cancellation through `cancel(task_id)`. The task executor
    /// is expected to remove the entry on exit via `clear_canceller`.
    pub async fn register_canceller(&self, task_id: &str, token: CancellationToken) {
        self.cancellers
            .write()
            .await
            .insert(task_id.to_string(), token);
    }

    pub async fn clear_canceller(&self, task_id: &str) {
        self.cancellers.write().await.remove(task_id);
