Auto-update / 自动升级
deskctl can now update itself in place — no re-cloning. It checks GitHub for a newer release at startup and tells you if there is one; it never downloads or changes anything on its own, and any failure to check is silent (no network, timeout, rate-limit — all skipped without a word). Turn the startup check off in settings or during install; the manual check now button still works either way. Replaced files are backed up first, and your recorded original desktop settings (~/.config/deskctl/) are never touched.
自动升级：启动时静默查一次 GitHub 有没有新版并告诉你，绝不自作主张下载或改动；查询失败（没网/超时/限流）一律安静跳过。可在设置或安装时关掉启动检查，手动检查按钮照常可用。被替换的文件会先备份，你那份"原始桌面设置备份"（~/.config/deskctl/）一概不动。
Everything else / 其余不变
The v2.1 taskbar controls (transparency, size, flattening) and desktop right-click menu settings are unchanged, as is the rule that everything goes through gsettings: no system file is modified, nothing needs root, and no extension is ever installed automatically. Restore Defaults still puts back your own values, not GNOME's.
v2.1 的任务栏控制（透明度、大小、展平）与桌面右键菜单设置保持不变；依旧全部通过 gsettings 完成——不改系统文件、不需要 root、不自动装任何扩展。「恢复默认」恢复的仍是你自己原来的值。
