Subject: [PATCH] =?UTF-8?q?chore:=20retire=20la=20section=20Score=20des=20?=
 =?UTF-8?q?Param=C3=A8tres=20et=20supprime=20la=20page=20Chat=20IA?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Section « Score Produit » retirée : elle ne faisait que décrire une formule,
  sans rien paramétrer.
- Page /admin/ai-chat et sa route /api/admin/ai-chat supprimées, ainsi que
  l'entrée de menu et la section « Admin AI Chat — Fournisseur » des
  Paramètres, qui n'existait que pour la configurer.
- Nettoyage de l'état devenu mort dans la page Paramètres : la liste des
  modèles Google et son chargement n'avaient plus d'interface.

Effet de bord notable : tsc passe de 23 à 4 erreurs préexistantes — la page de
chat en portait 19 à elle seule (flags de regex exigeant une cible es2018).

-- Application de gestion de gammes pour magasins Foirfouille Nancy
-- Gammes A/B/C/D/Z : A=pilier, B=bonne rotation, C=performance, D=saisonnier/niche, Z=sortie
-- Les ventes sont suivies par magasin (site) et par mois
-- Les utilisateurs arbitrent les classifications gamme par fournisseur
-
-## Stratégie d'analyse
-1. Si tu ne connais pas un code fournisseur ou un no_id, commence par chercher avec /api/fournisseurs?search= ou /api/articles?search=
-2. Enchaîne plusieurs appels \`call_api\` si nécessaire pour compléter l'analyse
-3. Pour le prix d'achat : utilise /api/articles?codefou=CODE (champ pa) ou /api/articles/:id/referentiel
-4. Pour le PRMP (prix réel) : utilise /api/stock/article/:id (champ prmp par site)
-5. Ajoute toujours \`limit\` pour éviter des réponses trop volumineuses (limit=20 à 100 selon le contexte)
-
-## Format de réponse — IMPORTANT
-- Réponds TOUJOURS en **Markdown** : titres ##, **gras**, tableaux \`| col | col |\`, listes \`-\`, blocs de code
-- N'utilise JAMAIS de HTML (<div>, <table>, <b>, <br>, etc.)
-- Réponds toujours en français
-- Sois précis, structuré et complet — ne tronque jamais ta réponse
-- Si les données sont nombreuses, résume et mets en avant les points clés`;
