Chatbot interface

A simple web interface for a chatbot.

To-do

Front-end:

• allow markdown for pretty stuff like code input (easy: <90m)
• light/dark theme (easy: <90m)
• pretty response rendering like in generative UI (medium: 1-3h)

Back-end:

• [IN PROGRESS] Conversation object actually contains the message history (easy: <90m);
• should route methods open and close a Redis client every time?
• Serve all routes (medium: 1-3h)
• Support other model providers like Together, possibly do this through Vercel AI SDK? (medium: 1-3h)
• Better usage of persistence layer, don't get/set every time you operate on conversation history (easy: <90m);
• Serve LM directly, not through 3rd party API (hard: >3h);
• IAM, with conversations stored per user and retrieved on login (hard: >3h);
