    fix: dev: Fix SERVFAIL for KEY queries at CNAME names in signed zones

    An authoritative server answered a query for the ``KEY`` type at a name
    holding a ``CNAME`` record with an empty answer instead of the ``CNAME``.
    In a DNSSEC-signed zone, validating BIND resolvers rejected that response
    and returned SERVFAIL. The ``CNAME`` is now returned, as for any other
    record type.
