/**
 * NestJS Streaming Module
 *
 * Provides SSE streaming integration for NestJS applications.
 * Can be used standalone or integrated with CoreModule.
 *
 * @example Standalone usage
 * ```typescript
 * import { StreamingModule } from '@plyaz/core/nestjs';
 * import { FilesStreamEndpoint, SystemStreamEndpoint } from '@plyaz/core/streaming';
 *
 * @Module({
 *   imports: [
 *     StreamingModule.forRoot({
 *       server: { heartbeatInterval: 30000 },
 *       endpoints: [
 *         { endpoint: FilesStreamEndpoint, config: { enabled: true } },
 *         { endpoint: SystemStreamEndpoint, config: { enabled: true } },
 *       ],
 *     }),
 *   ],
 * })
 * export class AppModule {}
 * ```
 *
 * @example Async configuration
 * ```typescript
 * StreamingModule.forRootAsync({
 *   imports: [ConfigModule],
 *   useFactory: (config: ConfigService) => ({
 *     server: {
 *       heartbeatInterval: config.get('STREAM_HEARTBEAT_INTERVAL'),
 *     },
 *     endpoints: [...],
 *   }),
 *   inject: [ConfigService],
 * })
 * ```
