feat(label): address labels by name and add import and clone

label edit bug and label delete kind/feature failed with "invalid resource
number", and label create took its name as --name and required
--color. Like gh, label create takes the name as an argument and picks
a random color without -c; label edit and delete take names or IDs
(delete several at once, after a confirmation that names them), and
-c/-d/-n/-f are the gh short flags. Without a name on a terminal, label
create asks for the name, color and description.

label list shows ID NAME COLOR DESCRIPTION FLAGS with a colored swatch
and exclusive and archived labels flagged. Mutations report ✓ lines.
label import reads a label file or stdin (label create --file still
works), label clone copies another repository's labels, skipping those
that exist unless --force, and label export writes to stdout by default
or to -O/--output.
