/**
 * recommend-heuristic.ts — the pure "which model should I use" pick,

 * touching node-llama-cpp or a real GGUF file.
 *
 * See recommend()'s own doc in index.ts for the honesty caveats this
 * heuristic carries (single-request serial measurement, no concurrency
 * model, fixed fraction/ceiling thresholds).
