Refactor devcontainer and MCP tools for containerized development

Ajout et configuration d’un environnement de développement conteneurisé (devcontainer) avec support multi-langages (Go, Rust, Python), intégration d’outils LLM locaux/cloud (LM Studio, Claude Pro), et refonte des outils MCP : suppression du module sandbox, correction de la gestion des chemins projet dans jj.py, ajout d’une fonction jj_new_tool, et structuration du Makefile pour le build multiplateforme. Mise à jour des scripts (docker-entrypoint.sh, setup-devcontainer.sh), du README.md et de bin/jj-ai-commit.sh pour automatiser la génération de messages de commit à partir des résumés des fichiers modifiés.
