model-check

Find the model that is currently best for a capability by reading the provider live catalogue, and record it with its source — the code asks for kinds, never hardcoded ids. Triggers on "/model-check", "which model should we use", "best video model right now", "is this model still current", "model staleness", "update the models", or before any production month and whenever a resolve comes back stale. Pairs with price-check — newest is not automatically best or cheapest.
