spec-kitty-implement-review

Orchestrate the implement-review loop for Spec Kitty work packages using any configured agent. Covers agent dispatch, state transitions, rejection cycles, arbiter escalation, and dependency-aware sequencing across all 13 supported coding agents. Triggers: "implement and review WPs", "run the implement-review loop", "orchestrate WP implementation", "dispatch agents for WPs", "coordinate implement and review", "sprint through WPs". Does NOT handle: specify/plan/tasks phases, setup or repair, glossary maintenance, or direct code editing by the orchestrator.
