tmux command: [`pipe-pane`](/en/tmux/latest/manual/pipe-pane/)

```
def pipe: (
  ?shell_command: ::String?,
  ?input: bool,
  ?output: bool,
  ?only_if_closed: bool,
  ?timeout: ::Numeric,
  ?cancel: untyped
) -> ::LibTmux::CommandResult
```

The shell command and its format expansion are explicitly requested here.
only_if_closed follows tmux -o: an existing pipe is closed, not retained.

Behavior contract: Pane pipes.
