Apple Silicon package file omits the AUR line
Pull request 16189, merged into quattro, takes the AUR repository out of the Apple Silicon pacman template. A Mac that is already installed keeps the line until omarchy-refresh-pacman or omarchy-channel-set rewrites the file.
That AUR repository serves 12 packages, and none of them is among the 171 that Omarchy installs on a Mac. The template becomes the package configuration on a new Mac image or install. No update step rewrites an existing file on its own.
