Developer builds two-model LLM debate system with asymmetric roles

1. Designate one LLM as the 'Thinker' to draft and defend an initial thesis on a complex topic.
2. Configure a second LLM as the 'Challenger' with strict instructions to only ask critical questions and expose assumptions.
3. Feed the Challenger's questions back to the Thinker to force iterative revisions over multiple cycles.
