feat(quickget): add architecture-aware output and filenames

- Display supported architectures when running ./quickget <os> (shows
"Archs: amd64 arm64")
- Add get_supported_archs() helper to enumerate available architectures
- Add arch_suffix() helper and append architecture suffix to VM
dir/config names
  for foreign architectures (e.g., alpine-v3.23-arm64/)
- Add NORMALISED_HOST_ARCH variable to detect foreign vs native
architecture
- Include arch="x86_64" or arch="aarch64" in config files for foreign
downloads
