3 people 87898d5eb3 feat: DNS host selection - system resolver, --dns-upstream flag, root hints ...

- Replace hardcoded 127.0.0.1:53 in systemResolver() with actual system
  DNS from /etc/resolv.conf (falls back to 127.0.0.1:53 if unavailable)
- Add Resolver field to RootDiscoveryConfig so callers can override the
  upstream resolver used during root server discovery
- Add --dns-upstream flag (e.g. --dns-upstream 8.8.8.8:53) to exploredns
  CLI and DNSUpstream field to Config
- Add internal/dns/hints.go with all 13 IANA root server IPv4/IPv6
  addresses as embedded constants (RootHints []RootServer)
- Update tests: fix real_exchange_test.go call site; add hints_test.go
  covering RootHints correctness and resolver helper functions
