`WakeTaskQueue` becomes `TaskQueue`, which carries the update itself. Delivery and waking are then one act: the winit host sends it through the `EventLoopProxy` as a `DefaultEvent::Update`, so there is no channel beside the loop and nothing has to claim a redraw is needed in order to be looked at. `Window::request_redraw` is gone from this path; `event` applies the update and then asks the tree whether anything became dirty, which is the same question `window_event` already ended with -- now `schedule_redraw`, called from both. The loop's message type is `DefaultEvent<State>`, so `Proxy` becomes a wrapper that takes the application's own `Event` and requires it to be `Send`, since it now crosses to the task thread by that route. The harness supplies a channel-backed queue, which is what lets a test hold updates until it asks for them. Tests split by subject -- layout, pointer, scroll, tasks -- with the region helper in `tests/common`.
