Integrate Mealie meal planning service into LangChain agent
Wires up the existing MealieService to the conversational agent with tools for querying today's meals, weekly meal plans, full recipes, shopping lists, and creating new meal plan entries. Adds env vars to docker-compose and updates the system prompt so the agent knows when to use each tool. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
