Add LLM Debate mode for multi-round iterative model discussions

Implements a debate feature alongside Council mode where 2-6 models
engage in multi-round discussions with configurable judge modes
(external judge, self-convergence, display-only), debate formats
(free discussion, structured opposition, iterative improvement, custom),
and early termination conditions.
