Problem:

running htmgo watch gives error upon changes in pages/index.go. Server doesn't reload.

Error:

Line 14 in 5d9c2f8

_ = os.RemoveAll(buildDir)

problem is here, for some reason on windows, the tmp-dir gets not cleaned before, prolly because of the fact that the exe is still in use.

existing := process.GetProcessByName("run-server")
if existing != nil {
	slog.Debug("process already running, killing it", slog.String("command", "run-server"))
	process.KillProcess(*existing)
	time.Sleep(time.Millisecond * 50)
}

yeah adding this first thing in func Server, fixes it.

thanks, I don't have windows right now so its hard for me to test. Would you be willing to make a PR with those fixes?
