//! Provider and model catalog: the compiled-in default catalog, its overlay
//! layers, and the resolution/query surface Harn uses to turn a selector into
//! a concrete provider/model identity.
//!
//! Split into bounded contexts: [`model_def`]/[`provider_def`] DTOs, the
//! [`config`] aggregate + merge, [`loading`] of ambient overlays, model
//! [`taxonomy`] + provider inference, the [`catalog`] query surface, selector
//! [`resolution`], and complementary-[`reviewer`] selection.
