tmux.Pane.SetCopyModePositionFormat(ctx: context.Context, value: string) -> error
```

SetCopyModePositionFormat stores the "copy-mode-position-format" pane option as string (tmux 3.6 or later). Read it with [PaneOptionValues.CopyModePositionFormat] from [Pane.Options]; [Pane.UnsetOption] restores inheritance or the global default.
