silverwind 34a2f682a5 fix(cmd): print only the error on CLI usage errors ...

cli v3.10 dumps the full command help to stdout on a usage error (unknown
flag, missing required flag, etc.). Take over that reporting via
OnUsageError so usage errors print only "Incorrect Usage: <err>" to
stderr and nothing to stdout, covering the auto-built completion subtree
through ConfigureShellCompletionCommand. Also stop RunMainApp from
printing the error a second time for non-unknown-flag usage errors.
