feat: implémentation complète du système Célestopol 1922 pour FoundryVTT v13

- DataModels (character, npc, anomaly, aspect, attribute, equipment)
- ApplicationV2 sheets (character 5 tabs, npc 3 tabs, 4 item sheets)
- DialogV2 pour les jets de dés avec phase de lune
- Templates Handlebars complets (fiches PJ/PNJ, items, jet, chat)
- Styles LESS → CSS compilé (thème vert foncé / orange CopaseticNF)
- i18n fr.json complet (clés CELESTOPOL.*)
- Point d'entrée fvtt-celestopol.mjs avec hooks init/ready
- Assets : polices CopaseticNF, images UI, icônes items
- Mise à jour copilot-instructions.md avec l'architecture réelle
