libtmux::Session::show_message(text: std::string_view) -> expected< void, CommandFailure >
```

Put a message on the status line of every client attached here, and send it to a control client as `message`.

tmux expands the text as a format, so a `#{...}` in it is substituted rather than shown. Text built from data belongs in `escape_literal` first.
