    fix(ci): refresh apt cache before cache-apt-pkgs-action lookup
    
    cache-apt-pkgs-action assumes apt package lists are already fresh, which
    isn't true on all runner images (e.g. ubuntu-slim), causing package
    resolution to silently return an empty list and liccheck to fail with
    "Packages argument is empty".
