tmux.PaneHookValues.PaneModeChanged() -> OptionValue[SparseArray[string]]
```

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