feat: Electron Windows 桌面客户端 v1.0
- 新增 electron/main.js: 主进程（窗口管理、系统托盘、原生菜单、IPC） - 新增 electron/preload.js: contextBridge 安全 API 暴露 - 新增 electron/desktop-bridge.js: 渲染进程桥接层 + Web 降级 - 新增 electron/desktop-integration.js: 菜单/托盘事件响应、原生文件对话框 - 更新 index.html: 集成桌面脚本 - 新增 package.json: Electron + electron-builder 配置 - 新增 DESKTOP_README.md: 桌面版开发文档 - 支持: NSIS 安装包 + 便携版、系统托盘、原生菜单、窗口记忆 - 安全: contextIsolation + IPC 白名单、单实例锁
