Addrinfo.getaddrinfo("localhost", 53, AF_INET, SOCK_STREAM) crashes
on GitHub Actions Windows runners with WSAHOST_NOT_FOUND, while the
same call works on Linux and macOS. Earlier hypotheses (winsock link
missing; hosts file not populated) have been ruled out on CI.
Probe five variants in one run to isolate the failing condition:
numeric literal 127.0.0.1, localhost with AF_UNSPEC, localhost with
nil family, localhost with AF_INET6, and the original AF_INET path.
Results go to stdout via puts so they are visible in CI logs. This
commit is temporary and will be reverted once the real fix lands.
