Aurora's own packages and repository

How Aurora's own .deb packages are built, signed and published.

• Choice: build/package-desktop.sh builds two .debs with dpkg-deb: aurora-desktop (everything that changes often, about 160 KB) and aurora-artwork (wallpapers and sounds, about 20 MB, rarely changes). tools/publish-apt.sh makes a signed apt repository (apt-ftparchive, InRelease and Release.gpg with an Ed25519 key) for GitHub Pages.
• Alternatives: a Launchpad PPA or OBS (tied to other distributions' infrastructure), reprepro, Flatpak for the desktop (a shell can't run sandboxed), no packages (installed systems would never get Aurora updates).
• Why: a plain static repository needs no server. apt already knows how to verify, upgrade and roll back packages, and a snapshot is taken before each upgrade anyway.
