 *   • `mock`               → {@link MockProvider} with NO canned responses; a
 *                            caller that actually drives it must pass one in (the

 *   • `openai-compatible`  → {@link OpenAiCompatibleProvider} against
 *                            `openAiBaseUrl`, key-less unless `OPENAI_API_KEY`
 *                            happens to be set (`providerLabel: 'openai-compatible'`).
 *   • `anthropic-api`      → {@link NotImplementedError} (raw API-key path, M5).
 *
 * @param config The parsed `llmMutator` config (reads `provider` + `model` plus
 *   the `openAi*` knobs for the OpenAI-compatible path).
 * @returns The constructed provider.
 * @throws NotImplementedError for `anthropic-api` (not yet implemented).
