Add dnsglobe (#357)

Adds [dnsglobe](https://github.com/514-labs/dnsglobe) — a global DNS
propagation checker TUI. It queries 34 public DNS resolvers around the
world in parallel, groups their answers (round-robin pools count as one
answer), shows per-resolver status on a braille world map, and has a
watch mode that re-polls until the record has propagated everywhere.
Built with ratatui + crossterm + tokio + hickory-resolver.

Entry is alphabetized within the section.
