 * 科大讯飞翻译类

 * 继承 BaseWebSocketClient，复用 WebSocket 连接管理、状态管理、错误处理等通用逻辑。
 * 专注于语音/文本翻译特有的功能：多语言支持、实时翻译结果、翻译模式切换等。

 * @example
 * ```typescript
 * const translator = new XfyunTranslator({
 *   appId: 'your-app-id',
 *   apiKey: 'your-api-key',
 *   apiSecret: 'your-api-secret',
 *   type: 'asr',

 *   to: 'en'
 * }, {
 *   onResult: (result) => console.log('翻译结果:', result),
 *   onError: (err) => console.error('错误:', err)
 * });
 *
 * await translator.start();
 * translator.record();
 * await translator.stop();
 * ```
