Add Grok CLI option

[emmi-dev12]

Many ppl would like to use Grok 4.5 via the cli, it would be nice if we could access that too in Buzz. Everybody who would like this feature, pls upvote or like or whatever.

It was added to the just released v0.5, but it doesn't work for me on Mac OS.
Grok Build is installed on my machine, but Buzz doesn't detect it.
Also, the "Setup guide" button points to a broken URL.
