I would love to see native support for Arch Linux update checking. Since Arch is a rolling release, keeping track of updates is crucial.

Ideally, the implementation should support:

1. Official Repository Updates (via pacman)
2. AUR Updates (via helpers like yay, which is very popular)

Describe alternatives you've considered
Currently, I have to manually check my Arch nodes or script custom solutions, but having it integrated into PatchMon would be much cleaner.

Additional context / Technical Suggestion
For Arch Linux, the safest way to check for updates without modifying the system database (to avoid partial upgrade issues) is using checkupdates (from the pacman-contrib package) or yay.

Here are the commands that could be parsed:

1. Official Packages (Safe check):
Requires pacman-contrib installed.

checkupdates | wc -l

Check for all updates (Repo + AUR)

yay -Qu | wc -l

It would be amazing if PatchMon could detect if pacman or yay is available and use the appropriate command to report the pending package count.

Thanks for your work on this project!
