Provide a few options for busy throbber

[Lenbok]

Just a quickie, see if you like it. I also wondered about renaming agent-shell--status-frame to agent-shell--busy-frame or agent-shell--busy-indicator-frame. I haven't tested under graphical header yet (I use tty).

Also allows eg:

  (with-eval-after-load 'nerd-icons
    (defun agent-shell-make-clock-outline-frames ()
      "Return a vector of nerd-font clock outline icons from one to twelve o'clock.
Uses the nf-md-clock_time_*_outline icons from the nerd-icons package."
      (vconcat
       (mapcar
        (lambda (hour-name)
          (nerd-icons-mdicon
           (format "nf-md-clock_time_%s_outline" hour-name)))
        '("one" "two" "three" "four" "five" "six"
          "seven" "eight" "nine" "ten" "eleven" "twelve"))))
    (setq agent-shell-busy-indicator-frames (agent-shell-make-clock-outline-frames)))

(ok that screenshot came out a bit wee)

lol, ok ;)

One thing, since we're now exposing the frames vector, perhaps we should expose it as a list instead which is more commonly known/used.

[xenodium]

agent-shell--status-frame to agent-shell--busy-frame or agent-shell--busy-indicator-frame

agent-shell--busy-indicator-frame SGTM

[Lenbok]

And :status-frame to :busy-indicator-frame in the header model, or leave as is?

[xenodium]

Ah. Yes. That too please.

[Lenbok]

Should be good to go.

@xenodium gentle nudge?
