* Fix multi-package removal in omarchy-pkg-remove
The script already had multi-selection enabled with --multi flag,
but wasn't handling multiple selections correctly. When users
selected multiple packages with Tab, they wouldn't all get removed.
Fixed by using xargs to properly convert newline-separated package
names from fzf into individual arguments for yay.
Fixes#805
* Add multi-select explainer
* Fix multi install like we did for remove
