AutoGen agents get stuck thanking each other and never terminate
Two AutoGen agents finish the task and then keep congratulating and thanking each other in a loop until the turn limit. The AutoGen FAQ calls this a 'gratitude loop' and attributes it to weaker models (it was observed with gpt-3.5-turbo) not remembering termination instructions.

Append an explicit termination notice to the task prompt so the model emits the termination keyword:
```python
termination_notice = (
'\n\nDo not show appreciation in your responses, say only what is necessary. '
'if "Thank you" or "You\'re welcome" are said in the conversation, then say TERMINATE '
'to indicate the conversation is finished and this is your last message.'
)
prompt += termination_notice
```
Also keep a hard cap on turns (e.g. `max_consecutive_auto_reply` / a termination condition) so a loop cannot run unbounded.
