* Only offer Update > Extra Themes when there is one
omarchy-theme-update pulls the themes under ~/.config/omarchy/themes that came from a git clone, so on a machine that has never installed one by hand the row opens a terminal that prints nothing and closes. Guard it with the same predicates the command itself applies, since a row that shows over a symlinked theme or a worktree's `.git` file is the same dead end in a narrower shape, and pin the two to each other in the guard test.

* Extract the Extra Themes guard into omarchy-theme-extras
The row's `when:` and omarchy-theme-update each carried their own idea of which themes came from a git clone, and the two only matched because a test held them together. Name it once instead: omarchy-theme-extras lists those directories and exits nonzero when there are none, so the row asks exactly the command its action runs. Living in a script also puts the glob out of reach of whatever shopt a login shell left set for the guard batch.
