feat: 为多个模块添加类型注解以增强代码可读性

为 ConnectionHandler 相关的函数参数添加类型注解，使用 TYPE_CHECKING 避免循环导入。主要修改包括：
- 在 abortHandle、textHandle 等处理模块中为 conn 参数添加 ConnectionHandler 类型注解
- 在 websocket_server、connection 等核心模块中为方法参数添加类型注解
- 在 plugins_func 下的多个功能模块中为函数参数添加类型注解
- 在 providers 相关模块中为工具执行器和方法添加类型注解
- 统一代码格式，如将单引号字符串改为双引号

Fixes #2034
