tmux.Window.SetPaneBaseIndex(ctx: context.Context, value: int64) -> error
```

SetPaneBaseIndex stores the "pane-base-index" window option as int64 (tmux 3.2a or later). Read it with [WindowOptionValues.PaneBaseIndex] from [Window.Options]; [Window.UnsetOption] restores inheritance or the global default.
