R2: git = source de vérité — src/nodes/ + build/extract intégrés au push

- src/nodes/*.js (6 nodes + template snapshot) = source de vérité unique.
- n8n-push.mjs reconstruit le JSON depuis src/ avant syntaxe+golden+PUT
  (src gagne toujours; n8n-extract.mjs pour resynchroniser si édition UI).
- n8n-build.mjs --check pour vérifier la synchro.
- Copies historiques déplacées dans archive/ (mortes, dérivées de la prod).
- .gitignore: backups locaux de rollback.
- AGENTS.md: règle R2 pour toutes les futures sessions (dont Qwen local).
- Validé: idempotence, mutation/restauration, pipeline push complet en réel.
