ci(portable): Skip execution checks for cross-arch artifacts

Make portable verification architecture-aware by checking the packaged\nnode-runtime architecture before running wrapper binaries. When host and\nartifact architectures do not match, keep structural validation and skip\nexecution checks to avoid cross-arch runner failures.\n\nCo-Authored-By: Claude <noreply@anthropic.com>
