Why: development-governance-v2 Phase 6 adopts the shared governance kit in every formal repository; the executor needs a valid AGENT-EXECUTION.md before any implementation unit can run.
Evidence: generated by dm-server governance init at Development-Manager bd3a7de57a3a9e1a4495b94c5fa5c08d71e7be8c; dm-server agent-exec validate passes.
Impact: configuration and task card only; no code or CI change yet.
