#16 issue list⇄close round-trip: list renders #1, close wants 1

Evidence: "f0rge issue list" prints "#1 open .."; "f0rge issue close #1" -> usage error. Copy-paste from list never works. Fix: set_state verbs (close/reopen/view/comment/assign/label/edit) accept "#N", "N", and uuid; or render list ids copy-safe. Acceptance: close "$(f0rge issue list | awk "NR==2{print $1}")" round-trips verbatim.
