io.github.libtmux.Server.Server.runShellCapturing(command: String) -> List<String>
```

Runs a shell command through tmux and answers with what it printed.

Separate from {@link #runShell} because tmux 3.3a and 3.4 run the command and then report
nothing, on every attempt. A caller who wants the effect is fine there; a caller who wants the
output would silently get none, so this one refuses rather than answering emptily.

tmux expands {@code #(...)} in this command before a shell sees it, and shell quoting does
not prevent that. Pass any interpolated value through {@link TmuxFormats#literal} unless you
mean it to be expanded.

## Raises

- `UnsupportedTmuxVersionException`: on the releases that lose the output
