op item edit can exit non-zero with "(404) Not Found" after an edit it
did save (seen with op 2.34.1 and 2.39.0 on an existing item), which
made opc report failure and skip the ops refresh. opc now reads the
field back and opd re-checks the item's labels, then prints either the
op:// reference it changed or what failed, op's message without its
timestamp prefix, and where to look next.
