 * OpenGateway provider built on `@ai-sdk/openai-compatible`.
 *
 * OpenGateway accepts OpenAI-compatible Chat Completions requests and routes
 * `owner/model` IDs such as `openai/gpt-4o-mini` or `google/gemini-2.5-pro`.
 * The plain AI SDK `reasoning` option is passed through as `reasoning_effort`.
 * `reasoning: 'none'` is left to the AI SDK default, which omits the field.
 *
 * @example
 * const opengateway = createOpenGateway();
 * await streamText({ model: opengateway('openai/gpt-4o-mini'), prompt: '...' });
