Refactor: 统一消息格式和Session架构重构

核心改动：
- 统一所有Session内部使用Claude content-block格式
- 引入BaseSession基类，简化代码结构
- tool_results从字符串改为结构化字典列表
- NativeClaudeSession增强：支持cr_token、metadata、thinking提取
- ToolClient简化：删除structured分支，统一使用protocol prompt
- MixinSession支持按名称选择session
- ljqCtrl_sop增加DPI坐标陷阱警告

 - **⚠️ 窗口坐标转换陷阱**：使用 `win32gui.GetWindowRect(hwnd)` 获取的矩形包含标题栏和边框，而截图内容是客户区。点击截图内元素时，必须用 `win32gui.ClientToScreen(hwnd, (0, 0))` 获取客户区原点的屏幕坐标，再加上截图内坐标。禁止直接用 GetWindowRect 左上角 + 截图坐标。
