 * SSE 文本解码插件 | A SSE (Server-Sent Events) response text decoder plugin.
 *
 * 用于处理服务端推送事件(SSE)的响应流,提供以下功能:
 * - 将二进制Buffer解码为文本
 * - 按指定分隔符拆分事件块
 * - 去除首尾空白字符
 * - 自动JSON解析
 * - 移除特定前缀
 *
 * Processes Server-Sent Events (SSE) response streams with the following features:
 * - Decodes binary buffer to text
 * - Splits event chunks by specified separator
 * - Trims whitespace
 * - Automatic JSON parsing
 * - Removes specified prefix
 *
 * @param {Object} [options] 配置选项 | Plugin options
 * @param {string} [options.splitSeparator='\n\n'] 分割符,用于拆分事件块(默认 '\n\n') | Separator for splitting events (default '\n\n')

 * @param {string} [options.doneSymbol] 结束标记,收到此标记时结束流(可选) | Symbol indicating stream end (optional)
 * @returns {HookFetchPlugin} 返回 HookFetch 插件实例 | Returns a HookFetch plugin instance
 * @example
 * request.use(sseTextDecoderPlugin({
 *   json: true,
 *   prefix: 'data:',
 *   splitSeparator: '\n\n',
 *   doneSymbol: '[DONE]'
 * }));
