Crate ailloli_ui_runtime

Retained-mode UI engine: element tree, layout, paint, input, and reactivity.

Pipeline for each frame (see Runtime::render_root on app::Runtime):

1. Reconcile: diff declarative component::View into an element::ElementTree
2. Layout: measure and position nodes (layout::LayoutEngine, layout::Widget)
3. Paint: emit scene::DrawCmd lists into a scene::Scene

Input is routed separately via input::InputRouter and widget component::Widget::event.

Modules

Module	Role
app	Runtime, RuntimeHandle, scheduler, state store
component	View, Signal/Memo/Binding, component builders
element	Retained element tree, keys, reconciliation
input	Hit-test, focus, pointer/keyboard routing
layout	Layout context, results, retained LayoutNode
scene	Draw commands, layers, clip stack, paint context
