Refonte complète en SvelteKit (méthode OKI, AI-Overview ready)

Reconstruit le site statique mono-page (Bulma + htmx + Strapi) en SvelteKit 2 +
Svelte 5 (runes) + TypeScript, 100 % statique (adapter-static), auto-hébergé.

- Contenu enrichi à partir du dossier documentaire sourcé : 28 pages (histoire,
  Mé 67, procès 1968, 9 fiches militants, idéologie, héritage, publications,
  charte, orientation, sources, FAQ, actualités, contact, mentions légales).
- Souveraineté : retrait de Bulma/htmx/mustache/ionicons/Plausible/Google Fonts
  et de l'API Strapi. Polices Archivo/Inter et sprite SVG auto-hébergés (zéro emoji).
- Identité GONG (drapeau vert/blanc/rouge), thème sombre par défaut + clair AA,
  cadences motion gwoka, KineticText, timeline, 404 kréyòl, PWA hors-ligne.
- SEO/AI-Overview : HTML sémantique, JSON-LD (Organization, Person, Event,
  FAQPage, Article...), hreflang, sitemap dynamique, robots/humans.txt.
- Sécurité : CSP hachée + en-têtes (.htaccess o2switch + _headers Cloudflare), HSTS.
- Actualités éditées via Sveltia CMS (git-based) ; Strapi retiré.

npm run build : vert · npm run check : 0 erreur / 0 warning · JS 97 Ko gzip.
