- Removed print() statement in event_listener.py that was printing all LLM streaming chunks to stdout
- The print() on line 386 was causing all text chunks from LLM responses to be displayed in stdout
- Added test to verify stream chunks are emitted as events but not printed to stdout
- Streaming chunks should only be handled by event handlers, not printed directly
Fixes#3715
