/**
 * @file Services Module Index
 * @description Central export for all service utilities including
 * HTTP clients, interceptors, caching, batching, versioning, and optimistic updates.
 *
 * This module provides a complete enterprise-grade service layer for React applications:
 *
 * - **HTTP Client**: Centralized HTTP client with interceptor support
 * - **Type-Safe API**: Contract-first API clients with Zod validation
 * - **Circuit Breakers**: Fault tolerance and service health monitoring
 * - **Offline Support**: Persistent queue for offline-first applications
 * - **Request Batching**: DataLoader pattern for N+1 query prevention
 * - **API Versioning**: Multiple versioning strategies with migration support
 * - **Optimistic Updates**: Seamless UI with conflict resolution
 * - **Enhanced Interceptors**: Tracing, retry, and telemetry
 *
 * @example Quick Start
 * ```typescript
 * import { initializeServiceLayer, serviceLayer } from '@/lib/services';
 *
 * // Initialize during app bootstrap
 * await initializeServiceLayer({
 *   apiBaseUrl: 'https://api.example.com',
 *   enableOfflineQueue: true,
 *   enableCircuitBreakers: true,
 * });
 *
 * // Use the HTTP client
 * const response = await httpClient.get('/users');
 *
 * // Use typed API clients
 * const userApi = createUserApiClient();
 * const users = await userApi.getUsers({ query: { page: 1 } });
 * ```
