fix(site): synchronise package-lock.json (@arboretum/site + @fontsource)

Le commit e7c1a60 a embarqué un package-lock.json antérieur à l'ajout du workspace @arboretum/site et de la dépendance @fontsource/jetbrains-mono : `npm ci` (ci.yml) aurait échoué. Régénéré via `npm install --package-lock-only` (purement additif, aucune autre dépendance touchée). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
