The OpenRouter model picker builds its list from a curated set of model
IDs, then filters against OpenRouter's live catalog. minimax/minimax-m3:free
exists on OpenRouter (free tier, 1M context, tool-calling) but was missing
from both the in-repo fallback list and the remote catalog manifest.
Add it to OPENROUTER_MODELS and website/static/api/model-catalog.json so
the free variant surfaces in the picker alongside the paid one.
