multi-llm-convergence

Drives any artifact (plan, PRD, design doc, spec, or implementation diff) to convergence by alternating two genuinely different LLM reviewers — a Codex reviewer and an independent Claude review subagent — applying each round's findings and looping until both independently agree it clears the bar. Grounds offline reviewers in local source-of-truth clones, runs a liveness watchdog so a silent reviewer can't hang the loop, and commits per round for an auditable trail.
