refactor: 桌面应用对话框代码拆分为平台专用文件
- 新增 dialog_windows.go、dialog_darwin.go、dialog_linux.go - 使用 Go 构建标签实现条件编译 - 修复跨平台编译错误（syscall.NewLazyDLL 在 macOS/Linux 未定义） - 实现 Linux 多工具降级策略（zenity → kdialog → notify-send → xmessage → stderr） - 实现 macOS AppleScript 字符转义 - 更新 messagebox_test.go 构建标签 - 更新 desktop-app spec 新增 Linux 降级策略和 macOS 字符转义规范
