让它真正像桌面 App 而非套壳网页:启用闲置的 Wails Go 桥,接原生文件框/系统打开/ 通知/无边框标题栏,且全部对浏览器预览(make web)优雅降级。 - app.go:SaveReportAs(原生"另存为"框 + 下载落盘)、OpenReport(下到临时目录 + 系统默认应用打开 docx)、Notify(macOS osascript 通知)、download/openInSystem 跨平台 - main.go:macOS TitleBarHiddenInset —— 隐藏标题栏、内容铺满到顶、保留红绿灯交通灯 - lib/desktop.ts:window.go.main.App 运行时桥 + isDesktop/isMacDesktop 探测; saveReportAs/openReport/notify 在无 Wails(浏览器)时分别降级为 <a download>/新标签/Toast - ReportView:桌面端「另存为 Word」(原生框) +「用系统打开」+ 完成弹系统通知; 浏览器端保持「下载 Word」 - KbView:拖拽文件入库(HTML5 dataTransfer,两种模式通用)+ 拖拽高亮 +「选择文件」按钮 - TopBar:顶栏设为 Wails 可拖拽区(--wails-draggable),控件标 no-drag; macOS 桌面端左留白让位交通灯 验证:GOWORK=off wails build 打出 .app(绑定生成 + mac 标题栏);启动真实原生窗口 截图确认无边框标题栏 + 交通灯内嵌 + 顶栏可拖拽(见会话截图);浏览器(Preview)确认 window.go 不存在时降级正确(下载链路 + 拖拽占位)。tsc + vite build 通过。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
