Add run-ubuntu2604.py with its QEMU config files and NoCloud seed. The launcher follows the Debian 13 one, with UBUNTU_VM_ settings and SSH forwarded to host port 2225. The seed injects the current user's SSH public key, uses the USTC mirror (ubuntu-ports on arm64) and installs the GNOME desktop on first boot. Update vm-images for the ubuntu2604 image target.
