When no UUID has been specified, query-uuid returns

    {"UUID": "00000000-0000-0000-0000-000000000000"}

The doc comment calls this "a null UUID", which I find less than
clear.  Change it to "an all-zero UUID".

Technically it's a "nil UUID";
https://datatracker.ietf.org/doc/html/rfc9562#name-nil-uuid

If you wanted to be pedantic, you could say "the nil UUID (all zeroes) is
returned"

but your rephrasing is clear even w/o using the standard name, so I'm fine
either way.
