Plusieurs gros ajouts :

- Possibilité de discuter avec un PDF ; RAG ou analyse approfondie. Enlèvement de l'autre outil PDF de discussion qui analysait d'abord un PDF en proposant directement une intégration sans attendre qu'on pose de question
- Mise en place de l'import directement dans les outils dans la sidebar
- Mise en place d'un outil pour créer des tables aléatoires avec possibilité d'utiliser pendant la partie
- Mise en place d'un outil pour mettre en place des PNJ, scènes, chapitre.... directement à partir de la discussion avec le PDF
- Mise en place RAG avec mistal-embeding ou nomic si on utilise ollama
- Mise en place mistral, google en fournisseurs alternatifs pour l'IA dans le cloud
- version 0.11.0-bêta
