feat: refonte OKI — constellation, carte SVG déterministe, timeline interactive

- Background : shader Three.js remplacé par la constellation zetwal (DOM/SVG, zéro WebGL)
- Carte : graphe 3D aléatoire remplacé par un SVG 2D au layout baké au build
  (scripts/build-layout.mjs, positions déterministes), nœuds focusables, pan/zoom, filtres sans re-layout
- Timeline : 4 ères, reveal syncopé gwoka, liens événement→fiche catalogue (module software-modal),
  mois affichés, corrections factuelles (Twitter 2022, Mastodon 2016, PeerTube 2017, Bluesky 2024, 105 logiciels)
- Charte OKI : tokens + bridge, Archivo/Inter self-hébergées, flag-bar, KineticText, footer fédéré
- Dette : three retiré (JS initial ~828 Ko → 77 Ko), OG/Twitter/JSON-LD/robots/sitemap,
  licence CC BY-SA 4.0, fediverse.json mort supprimé, icônes PWA 121 Ko → 9 Ko
- Lighthouse mobile : 91/97/100/100 — tests vitest 6/6, svelte-check 0/0
