Introduces DistroProfile catalog (9 distros: Debian, Ubuntu 20/22, Rocky 9, CentOS 7, Alpine, Fedora, Kali, Arch) with distro-styled hostname generation. Adds --distro and --randomize-distros CLI flags, a `decnet distros` listing command, and fixes composer.py which was ignoring per-decky base_image in favour of a hardcoded Debian constant.
