review

Universal review with narrative verdicts for consistent quality gates before and after implementation. 6 parallel reviewers: 2 internal (Security, UX/DX) via Task + 2 external slots via available providers (Codex/Gemini CLI, Claude Task fallback) + 2 domain experts via Task. Graceful fallback when CLIs are unavailable. Modes: --mode clarify/plan/code. Triggers: "/review"
