Tracks tagged releases from the quickshell-mirror GitHub repository through an upstream watch, so new versions arrive via sync-upstream. The recipe follows Arch's extra/quickshell, builds for x86_64 and aarch64, ships the Qt compatibility check hook, and rebuilds on Qt updates like quickshell-git. It conflicts with quickshell-git.
