Resume Agent Run Stream
Resume an SSE stream for an agent run after disconnection.
Sends missed events since last_event_index, then continues streaming live events if the run is still active.
Three reconnection paths:
- Run still active: Sends catch-up events + continues live streaming
- Run completed (in buffer): Replays missed buffered events
- Run completed (in database): Replays events from database
Client usage:
Track event_index from each SSE event. On reconnection, pass the last received event_index as last_event_index.
