libtmux::Pane::leave_mode() -> expected< void, CommandFailure >
```

Leave whatever mode the pane is in.

A pane in no mode is refused, with tmux's "not in a mode". That is kept rather than smoothed into success: checking first would cost a round trip and still race, and a caller who cares can read `in_mode` or ignore the failure.
