Module catalog 

Compile-time model catalog hydrated from models.dev + liter-llm provider registry.

The catalog is embedded at build time by build.rs as a JSON blob via include_str!. It provides typed access to provider routing data, model capabilities, pricing, and context limits — used by the [ProviderRegistry], model router, and admin UI.
