桌面 GUI 外链修复 + 主题顺序调整（含结构扁平化进行中的工作区基线）
- 集成 tauri-plugin-opener：Cargo/lib.rs/capabilities/npm 四处接线，新增 src/openExternal.ts（桌面走 opener，浏览器回退 window.open，相对路径绝对化） - 关于页 4 个链接、活动栏官网菜单、代理错误横幅 2 处健康检查链接全部改走 openExternal，桌面端可正常跳转 - 设置→外观 主题顺序调整为 深色/浅色/跟随系统 - release 二进制重编并验证（浏览器实测关于页链接可开文档页） - 附带工作区中未提交的扁平化重构现状（另一会话进行中） - homepage 落地页与文档终检通过（8787 / 与 /docs 双 200）
