Model catalog generator

Run from the repository root:

go generate ./llm

The generated llm/catalog.generated.json is committed and embedded by catalog.go, so normal builds and application startup do not need network or filesystem access.

The generator draws on several public catalog layers:

• Models.dev is the primary source. It is an open-source database created by OpenCode and maintained as provider/model TOML files in sst/models.dev.
• OpenRouter supplies its live routed model catalog and pricing.
• Vercel AI Gateway supplies its live gateway catalog and pricing.

These are catalog aggregators, not authoritative model vendors. Provider API documentation remains the source of truth when metadata conflicts. Local normalization and compatibility overrides live in main.go and should stay small and explicit.

Only models whose protocol is implemented by the Go package are emitted. Currently those protocols are openai-completions and anthropic-messages. The generated JSON is grouped by provider at the top level.
