tmux.WindowHookValues.PaneTitleChanged() -> OptionValue[SparseArray[string]]
```

PaneTitleChanged returns materialized "pane-title-changed" as [OptionValue] with value type OptionValue[SparseArray[string]] from window hook values; it does not query tmux. Available as COMMAND since tmux 3.2a. Its present SparseArray value preserves assigned tmux indexes, including gaps.
