/**
 * One place that turns resolved config into a {@link ChatModel}. `provider` names
 * the WIRE FORMAT, not a vendor: `openai` speaks the OpenAI-compatible API (point
 * `baseUrl` at OpenRouter, Fireworks, a LiteLLM proxy, Groq, a local server, …),
 * `anthropic` speaks the native Messages API. Adding a vendor is a base URL, not
 * a code change; adding a wire format is one new adapter here.
 *
 * `litellm` is a convenience over `openai`: same wire format, but pointed at a
 * LiteLLM proxy by default and paired with `/v1/models` auto-discovery
 * (see litellm.ts), so one endpoint reaches 100+ providers.
 *
 * `orcarouter` is the same kind of convenience over `openai`, pointed at the
 * OrcaRouter AI gateway by default (see orcarouter.ts) so its users get the
 * gateway's routing, failover, and guardrails behind a named provider instead
 * of a bare custom base URL.
