Build a live ISO too, and put it in releases

live/: quine-linux plus the live session and Anaconda WebUI, adapted from Aurora's live ISO (get-aurora-dev/iso); Titanoboa's script packs it into the ISO. The installer installs quine-linux:latest from inside the ISO, and plasma-setup creates the first user at first boot, as on the disk image. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
