+// Event emitter for broadcasting new events to SSE clients
+// Used by:
+// - subprocess-manager.ts: emits events received from event-subprocess via IPC
+// - api/activity/events/+server.ts: listens for events to broadcast via SSE
+export const containerEventEmitter = new EventEmitter();
+
+// Allow up to 100 concurrent SSE listeners (default is 10)
+// This prevents MaxListenersExceededWarning with many dashboard clients
+containerEventEmitter.setMaxListeners(100);
