 * Static service discovery for simple cloud deployments
 *
 * Use this when:
 * - Running on AWS Elastic Beanstalk, Heroku, Railway, Fly.io, etc.
 * - You have static/known service URLs
 * - No dynamic service discovery infrastructure (no Consul, K8s, etc.)
 * - Services are configured via environment variables
 *
 * Example environment variables:
 * ```
 * USER_API_URL=https://user-service.elasticbeanstalk.com/api/users/
 * ORDER_API_URL=https://order-service.us-east-1.elasticbeanstalk.com/api/orders/
 * PAYMENT_API_URL=https://payment.myapp.com/api/payments/
 * ```
 *
 * Or using a config object:
 * ```typescript
 * const discovery = new GGStaticServiceDiscovery({
 *   UserApi: 'https://user-service.elasticbeanstalk.com/api/users/',
 *   OrderApi: 'https://order-service.elasticbeanstalk.com/api/orders/'
 * });
 * ```
