/**
 * Honest fallback note for the LLM-as-judge CLI commands.
 *
 * The judges fall back to deterministic scoring when the LLM call fails (out of
 * API credits, network error, model unavailable). Without a signal, a user who
 * set a key and asked for the LLM judge cannot tell that apart from the legitimate
 * "no key → deterministic" case. This surfaces a one-line note to stderr ONLY when
 * the LLM path was genuinely requested (a key is present, and where applicable the
 * user opted in) yet every result came back deterministic — i.e. the call failed.
 * It writes to stderr so `--json` stdout stays pure.
