Struct StreamStoppedEvent

pkg/runtime/event.go:499–505

StreamStoppedEvent reports that a RunStream loop has stopped. Reason carries the turnEndReason* classification (normal, error, canceled) so consumers can tell successful completion apart from crashes and user-initiated stops. Delivery is best-effort: it is emitted non-blockingly during teardown and

// the guaranteed terminal signal. Do not assume session-end hooks have finished
// when this event arrives: it is emitted before they run.
