```
server.discovery.Server.windows_or_empty(self) -> Vec<Window>
```

List every window on the server, in tmux's own order.

A window linked into several sessions appears once per link, so a
window id can repeat. See [`Window`] for what that means for equality.

This is the lenient form; use [`Server::windows`] when the reason
for an empty result matters.
