- /agent page: chat UI with provider picker (HF Inference Providers + OpenRouter),
visitor's API key held in-browser and proxied per-request (never stored),
full live model catalog with tool/free filters + context length (find the 1M
free models), and a teaching system prompt.
- Browser tool-loop executes WEED-SIM's own API as tools on the user's live
session (load/grow/breed/clone/germplasm/predict/bus) — fully associative.
- Backend /api/agent/chat + /api/agent/models proxy both routers (OpenAI-compatible).
- Nav + route manifest updated.
