tmux.Pane.SetPaneColours(ctx: context.Context, value: SparseArray[string]) -> (SetArrayResult, error)
```

SetPaneColours replaces the complete "pane-colours" pane option array with SparseArray[string], preserving holes and empty values (tmux 3.3 or later). Read it with [PaneOptionValues.PaneColours] from [Pane.Options]; [Pane.UnsetOption] restores inheritance or the global default. Replacement is not atomic: the result reports confirmed writes, and failures stop without rollback. Serialize concurrent replacement of the same target and option.
