v3 : socle Rust (moteur pur, accès trustinWallet, serveur) ; maquette Nuxt rangée dans maquette/

- crates/ld-engine : formule inertielle (parité avec la maquette, garde C),
  coquille / changement de fond, assistant d'édition à règles, composition
  d'un document sous vote permanent (adoptions, aperçus, rivales).
- crates/trustin-access : qui voit, qui ouvre, qui gère les accès.
- crates/ld-server : API axum + SQLite, connexion Ğ1 (client OAuth2 de
  connect.monnaie-libre.fr), invitations, entrée en vigueur automatique,
  signalements de contradiction, traductions éditoriales, publication git,
  taille de la toile lue sur la chaîne.
- seeds/acte-engagement-certification.json : 33 articles, fr + en + es ;
  en vigueur : préambule, E1, E2 (seed a minima).
- maquette/ : frontend, backend et docker v2 déplacés tels quels.
