//! Inbound OpenAI Models adapter: `GET /v1/models`.
//! Lists everything a client can address: the virtual `cortiq-auto`, the
//! configured `[[models]]` pool, and the managed local `[[cmf.servers]]`.
//!
//! The managed CMF servers belong here because they are routable model ids like
//! any other — omitting them left OpenAI clients (Open WebUI among them) unable
//! to pin a local model even though the gateway would happily serve it.
