```
Server.link(_:into:)(window: Window, into: Session) -> WindowLink
```

Links a window into another session. The same window then appears in both, sharing one id — which is tmux's model, not a copy. The source is global because no existing session-local appearance is involved.

## Raises

- `TmuxError`
