fix(discovery-plugin): handle smallcaps # prefix in readResponseKind

CapData bodies are smallcaps-encoded JSON with a leading '#' marker, so
the previous JSON.parse(body) always threw and the catch returned
undefined — making 'kind !== public' true for every response and
rejecting every public contact as non-public. Match the kind field by
regex against the raw body, the same way extractKref reaches into it.
