Config locale : .mcp.json, CLAUDE.md, skills n8n opencode

Ajout de la configuration MCP (5 serveurs n8n) et du CLAUDE.md qui charge
AGENTS.md/HANDOFF.md/MEMORY.md/docs/MANUEL_COMPLET.md, ainsi que les skills
n8n de référence (.claude/skills/*, docs uniquement, pas de code exécuté).
.claude/settings.local.json reste ignoré (déjà dans .gitignore).
