v0.5.1

Critical fix

The default base_url was missing a trailing slash, so RFC 3986 / PSR-7 URI
resolution dropped the /api/v1 path prefix and every request hit the
marketing 404 page instead of the API. All users on the default endpoint
must upgrade.

What changed

• Default base_url now ends with /, and all internal paths are relative.
• Constructor normalizes a custom base_url without a trailing slash,
  so user-supplied endpoints work too.
• Regression test asserts the full request URI for every endpoint
  (domain, ip, asn, nameserver, entity, tlds, tld).
