`node-lookup -jF ipaddress,enc_role` returned `{}` because it queried a single
fact literally named "ipaddress,enc_role". Requesting several facts per host is
a natural need (e.g. pairing an address with its role).
- Split -F on commas (splitFactNames) and match any of them via an "or" over
["=","name",<n>] clauses (nameFilter); a single name keeps the plain "="
form.
- Key JSON output by each result's real fact name so all requested facts appear
under the host (previously keyed by the raw -F string).
- Update the -F flag help and add unit tests (split, single vs multi query
shape, multi-fact JSON).
