tmux.Window.SelectLayout(ctx: context.Context, request: SelectLayoutRequest) -> error
```

SelectLayout applies one layout operation to the receiver's exact winlink. It changes pane geometry without selecting the window or promising client focus. The materialized receiver is not refreshed, so callers that need current pane geometry must obtain a new snapshot or refresh related models. A transport or context error can be delivery-ambiguous; the void result cannot carry partial state and no rollback is attempted.
