feat:. mockSocketService 添加 connecting 状态

Browse Source 
- 新增 connecting 标志防止重复连接
  - 在 connect() 方法中检查 connected 和 connecting 状态
  - 连接成功或失败后清除 connecting 标志\
2. NotificationContext 调整监听器注册顺序

  - 在 useEffect 中重新排序初始化步骤
  - 第一步：注册所有事件监听器（connect, disconnect, new_event 等）
  - 第二步：获取最大重连次数
  - 第三步：调用 socket.connect()
  - 使用空依赖数组 [] 防止 React 严格模式重复执行\
3. logger 添加日志限流

  - 实现 shouldLog() 函数，1秒内相同日志只输出一次
  - 使用 Map 缓存最近日志，带最大缓存限制（100条）
  - 应用到所有 logger 方法：info, warn, debug, api.request, api.response
  - 错误日志（error, api.error）不做限流，始终输出\
修复 emit 时机确保事件被接收

  - 在 mockSocketService 的 connect() 方法中
  - 使用 setTimeout(0) 延迟 emit(connect) 调用
  - 确保监听器注册完毕后再触发事件\
