--locked is unreliable for -git packages where Cargo.lock may diverge
from the latest source. Also documents the required paru -Sy --pkgbuilds
step and common error resolutions.
Add PKGBUILDs for moonset-git, moonlock-git, and moongreet-git.
Intended as a paru custom AUR source for easy installation of
all Moonarch components via `paru -S moonset-git`.
