/**
* Production ModelClient adapter (Hard Rule #18 — NOT unit-tested; validated on a real
* VPS/account). Wraps the server executor: builds a minimal non-stream chat body, calls
* `getExecutor(provider).execute(...)`, reads the response text + (best-effort) usage cost.
*
* The pure runner depends only on the `ModelClient` interface; this adapter is the single
* place that touches credentials, the executor, and Response parsing — so the eval stays
* faithful to production while the runner/scorers remain fully testable with a stub.
