The `--json` flag accepts a list of GraphQL fields to query for and
output in JSON format. To get the list of available flags, run the
command with a blank value for `--json`. Additional `--jq` and
`--template` flags are available just like in `gh api`.
For metadata types chosen in interactive flow, we fetch all records from
the API in order to be able to display a multi-select interface.
For metadata defined via command-line flags, we resolve records that can
be looked up directly, avoiding fetching the entirety of expensive
datasets (e.g. all members of an organization) if we can.
The new approach ensures efficient fetching when interactive flow is
combined with values from flags.
