When a newer image is on the forge, Kickoff shows "A system update is
available" with Update Now (Aurora's System Update); once one is
downloaded, "Restart to finish updating" with Restart. Hidden otherwise.
- patches/kickoff/: Kickoff's QML plus UpdateBar.qml as its footer. The
kickoff-builder stage rebuilds just that plugin from the image's own
plasma-desktop version (KDE's source, via the forge's
mirror-kde-plasma-desktop) and the final stage swaps it in.
- quine-update-check (root; bootc needs it): bootc upgrade --check, then
writes /run/quine-linux/update-status.json for the bar. At boot, every
4 hours, and after uupd's nightly update.
Tested in a VM from a disk image of this tree: up to date (hidden),
available and staged.
