Make a mistyped subcommand under a group command an error (closes #319)

snapshot, config, remote, database and completion had no Run, and
cobra checks a command's arguments only when it has one, so `vaultik
snapshot craete` printed the group's help and exited 0. Each group now
prints its help only when given no argument; any other word fails as
an unknown command with exit 1, as at the top level.

cobra adds the completion command only when Execute runs, so the root
command now adds it itself to give it a Run. Its scripts then go to
os.Stdout as it was at that moment; a later SetOut does not redirect
them.

Judgement call: the error has no "Did you mean" suggestion, which the
top level gives.

Model: opus-5-5

-  `prune` then removed the local snapshot records and deleted every blob,
