A node that emits a fixed queue of updates, one per activation.

The first activation returns the first update, the second the second, and so on; once the queue is drained every later activation re-emits the last update (so the node stays well-defined inside a loop). An empty queue makes every activation fail with TinyAgentsError::Graph.
