tmux.Window.SetCopyModeLineNumbers(ctx: context.Context, value: CopyModeLineNumbers) -> error
```

SetCopyModeLineNumbers stores the "copy-mode-line-numbers" window option as CopyModeLineNumbers (tmux 3.7 or later). Read it with [WindowOptionValues.CopyModeLineNumbers] from [Window.Options]; [Window.UnsetOption] restores inheritance or the global default.
