Debian/AlmaLinux/Fedora image filenames, URLs, and checksums were
hardcoded to arm64/aarch64 (for Apple Silicon macOS), which would
silently download the wrong-architecture image on an Intel/amd64
host. Detect the architecture from the host (uname -m), normalized
to arm64/amd64, with VM_IMAGE_ARCH as an override; the run-*.sh
scripts in the parent repo use the same override so both stay in
sync. amd64 keeps the previously pinned checksums; arm64 checksums
are still unpinned pending upstream publication.
windows11 is unaffected: it stays x86_64-only, matching run-windows11.sh.
