Could there be programmatic ways to help users characterize the safety of the AUR packages they install?

It says what the malware does, it's a remote access toolkit... It gives control of your machine to the malware operator. The malware operator could have done anything with that access... There's no way for the maintainers to know what was done on any given infected machine.
Announcements like this typically contain information that will help users identify if they were compromised, such as the name of files that are dropped or modified when the malware is initialized, startup entry names, etc. Obviously the person with remote access can get in and manually start doing things on individual machines, but that doesn't mean there aren't indicators present from the programmatic actions the m…
Also, an attacker may leave no traces by simply dumping the payload to /tmp.

Assuming the malware doesn't clean up after itself, `pacman -Q firefox-patch-bin librewolf-fix-bin zen-browser-patched-bin` would tell you if they are installed... but if it did clean up after itself... how are the maintainers supposed to know what steps were taken to clean up given that it's a rat that could be running different steps on different computers...

You might be able to poke at the PKGBUILD on the wayback machine and see if the original sources work.
ETA: According to a Reddit post linked elsewhere in this thread, the payload was a binary file downloaded by a python script in the repository. It has been uploaded to VirusTotal, but downloading requires a premium subscription according to their docs: https://www.virustotal.com/gui/file/d9f0df8da6d66aaae024bdca...
