Drives the full multi-agent design debate lifecycle: loads config, initializes the workspace, runs optional clarification, executes debate rounds (proposal, critique, refinement), dispatches the judge for convergence checks, and writes the final synthesis. Use when the user wants to start or run a design debate.
Evaluates convergence across agent refinements and, when the debate ends, writes the final synthesized solution. Operates in two modes: convergence_check (per-round verdict) and synthesis (final output). Use when the orchestrator needs a convergence verdict or a final synthesis document.
