NaN Open WebUI

A ChatGPT-style interface packed in Docker and wired to the NaN API. The catalog includes qwen3.6, glm5.2, deepseek-v4-flash, mimo-v2.5, gemma4, whisper, kokoro, qwen3-embedding and flux-2-klein. It runs chat with history, vision, web search with self-hosted SearXNG, voice, a code interpreter, document RAG and image generation. Chats and accounts stay on your machine; the API key lives in `.env`. One `docker compose` and it is up.
