feat(cli): account, rm -r and mkdir, Tab completion

account shows the account and does what the sign-up form and the Profile
page do: register (the passphrase floor and the hub's proof of work checked
here, the recovery key printed once), verify, change the passphrase, reset a
forgotten one, change the e-mail address, sign out everywhere, delete. A new
passphrase carries the copy of the account's keys each node keeps for
browsers first — opened under the old M, the same keys sealed under the new
one — and only then tells the hub; a refusal sets the copies back. A reset
restores them from the recovery copy. The connections that do it never make
keys nor ask for a device approval. This machine keeps the M it changed away
from, so a node out of reach is carried at its next connection; a copy under
an M it does not know is no longer rewritten, which locked the browsers out
after a passphrase changed elsewhere.

rm -r removes a folder and all it holds, from the node's operator key: the
files, then the folders deepest first, one confirmation that counts them.
mkdir makes folders, --parents the missing ones (not -p, the passphrase).

completion bash|powershell prints the script that makes Tab complete actions,
verbs, options and the paths of the groups this machine is signed in to,
cached two minutes; the deb and rpm packages install the bash one.

+`$PROFILE`. It never asks for anything: on a computer that is not signed in,
+it completes actions and options only.

 Managing a node is not the client's job: that is `meshbay-node` (§6).
