/**
 * Tauri adapter for {@link LayoutGateway} (L4). Together with the sibling
 * adapters this is the *only* place that calls `invoke()`; components reach it
 * exclusively through the port.
 *
 * Commands and payload keys are camelCase, matching the backend DTO convention.
 * The `load_layout`/`mutate_layout` commands return the layout tree directly
 * (the backend `LayoutDto` is `#[serde(transparent)]` over the tree).
