cd: container-native Linux packaging (deb/rpm/pacman) + AppImage

Each distro package builds inside that distro's container so declared
dependencies always resolve to native names: hand-rolled deb via
dpkg-shlibdeps + dpkg-deb, rpm via rpmbuild's auto-requires, Arch via
makepkg (non-root builder user). git/curl install before checkout
(container jobs). AppImage keeps cargo-packager on the Ubuntu runner.
The release gates on all four package jobs plus macOS/Windows.
