AI Debate Mode: Enable Multi-Model/Agent Iterative Discussion

Add a feature that allows two (or more) selected AI models or agents to automatically discuss, critique, and debate each other's responses to a prompt. The models would take turns replying to, questioning, or improving upon each other’s answers until a consensus or stopping condition is reached. The entire conversation should be visible and exportable to the user. This would help users get more accurate, robust, or creative solutions through collaborative AI reasoning.
