- Rename `isPublicUse()` to `isGloballyReachable()`, conforming to the official
wording used in the IANA special-purpose address registries ("Public Use"
does not appear in them). Keep `isPublicUse()` as a deprecated alias.

P2 Missing @deprecated on concrete implementations

The @deprecated annotation exists on IpInterface::isPublicUse() but is absent from the concrete implementations in IPv4, IPv6, and Multi. IDEs and static analysers (PHPStan, Psalm) resolve deprecation warnings from the declared type at the call site. When user code holds a variable typed as the concrete class rather than IpInterface, the tooling will silently accept isPublicUse() calls without any deprecation notice, defeating the purpose of the annotation.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

P2 No test coverage for the deprecated isPublicUse() alias

All three test classes (IPv4Test, IPv6Test, MultiTest) had their testIsPublicUse methods renamed to testIsGloballyReachable, which now only exercises the new method. The deprecated isPublicUse() delegate is completely untested — a future refactor that accidentally breaks the delegation (e.g., returning a hardcoded value) would go undetected. A minimal parameterised test that calls isPublicUse() and asserts it matches isGloballyReachable() would guard the alias.
