/**
 * Core Dependencies Configuration
 *
 * Similar to @plyaz/api's setGlobalConfig pattern.
 * Backend services are registered here by entry points, not imported directly.
 *
 * IMPORTANT: This file must NOT import from backend service files (DbService, CacheService, etc.)
 * as that would cause the bundler to include backend dependencies in the frontend bundle.
 *
 * @example
 * ```typescript
 * // entry-backend.ts
 * import { setCoreDependencies } from './config/dependencies';
 * import { DbService } from './services/DbService';
 * import { CacheService } from './services/CacheService';
 *
 * setCoreDependencies({
 *   DbService,
 *   CacheService,
 *   StorageService,
 *   NotificationService,
 * });
 *
 * // entry-frontend.ts
 * // Don't call setCoreDependencies - no backend deps loaded
 * ```
