tmux.GlobalWindowScope.SetWindowSize(ctx: context.Context, value: WindowSize) -> error
```

SetWindowSize stores the "window-size" window option as WindowSize (tmux 3.2a or later). Read it with [WindowOptionValues.WindowSize] from [GlobalWindowScope.Options]; [GlobalWindowScope.UnsetOption] restores inheritance or the global default.
