Struct AgentRunHandle 

pub struct AgentRunHandle {
    pub instance_id: String,
    pub final_result: Receiver<Result<AgentRunResult, String>>,
}

Handle returned by run_agent. The caller already holds the mpsc::UnboundedReceiver<AgentEvent> they paired with the tx passed into run_agent; this handle adds the structured terminal value via final_result (drone Agent block’s downstream output) and the instance_id of the backing db_agent_instances row.

Dropping the caller’s receiver implicitly cancels the run only if the runner observes the send error — Phase 2 adds an explicit AbortHandle.
