Étape 1 : squelette du projet

- Monorepo backend/ + frontend/ + deploy/
- Backend FastAPI/SQLModel/Alembic/uv qui démarre (health check, config,
  i18n, base de test PostgreSQL, pytest)
- docker-compose de développement (db + backend hot-reload)
- Chaîne CI/CD GitHub Actions : lint + tests, build image, push GHCR,
  déploiement SSH sur le VPS à chaque push main
- CLAUDE.md : vocabulaire du domaine, conventions, commandes
