feat(oki): intro publique, chimen, PWA offline, contribuer, kréyòl, ton OKI

- Landing : intro « Pourquoi ce site ? » (Chat Control expliqué au grand
  public) + sommaire-chimen en 3 arcs (Fondations 🟢 / Reprendre le
  contrôle 🟡 / Autodéfense avancée 🔴) avec compte d'outils par catégorie
- PWA : service worker offline-first (précache coquille, network-first
  avec repli cache pour les fiches consultées), badge hors-ligne discret
- Page /contribuer (3 voies + forge labola) + template d'issue Forgejo
  .gitea/ISSUE_TEMPLATE/nouvo-zouti.yaml ; liens GitHub → labola.o-k-i.net
- Fiches jumelles créoles : chargeur content/outils/gcf/, affichage selon
  la langue avec bandeaux « an chantyé » / « póko tradui », 6 pilotes
  (signal, protonmail, brave, bitwarden, ublock, quad9) — À FAIRE RELIRE
  par un locuteur natif
- Ton OKI : les 6 mêmes fiches réécrites (tutoiement, registre
  militant-chaleureux) ; le script de migration n'écrase plus les fiches
  retravaillées (--force pour tout régénérer)
- UI : View Transitions (respect reduced-motion), aide clavier « ? »
  (dialog natif, raccourcis / h a), progression locale « jès fèt »
  (localStorage uniquement, compteur visible après le premier geste)
- docs/DEPLOYMENT.md : guide VPS (Caddy, nginx, YunoHost, Docker, rsync)
- Audits : axe-core 0 violation (5 pages), Lighthouse 99-98/100/100/100 ;
  corrections contraste monogrammes + ordre des titres
- Budgets : JS 46 Ko gzip, CSS 3,5 Ko, 59 pages prérendues
