The remote commands are the only code in mgsh that can destroy data, and
they were the least verifiable: each one is a single string handed to a
login shell, so a missing quote silently changes which paths it touches.
Every one of them now goes through the sshExec variable, and yesno is a
variable too, so a test can record what would have been sent and answer
the confirmations without a terminal.
The tests pin down what the previous commit fixed by reasoning alone:
that a declined or unreachable `init` sends no rm -rf, that a project
named "my 'weird' project" reaches the server fully quoted, and that
archive's cp/tar/rm sequence is named, ordered and quoted correctly.
push is driven end to end against a real local bare repository.
archive also gained the server-side existence check that init, clone and
show already had, so a project that was never pushed reports that instead
of failing inside cp -r.
