   * The underlying HTTP client capable of communicating with the OpenRouter API.

   * This client is pre-configured with authentication, base URL, and standard
   * headers required for OpenRouter API communication. It provides direct access
   * to the generated OpenRouter API client for operations not covered by the
   * higher-level methods.
   *
   * Use this when you need to:
   * - Access provider-specific API endpoints not available through the AI SDK
   * - Implement custom request/response handling
   * - Use OpenRouter API features not yet supported by the Effect AI abstractions
   * - Perform batch operations or non-streaming requests
   *
   * The client automatically handles authentication and follows OpenRouter's
   * API conventions for request formatting and error handling.
