LayoutNodeFocusAdapter

class LayoutNodeFocusAdapter(val node: LayoutNode) : GuiEventListener

Bridges one FocusableModifier-carrying LayoutNode into vanilla Minecraft's GuiEventListener focus graph, so vanilla's Tab/Shift-Tab and arrow-key navigation - and anything else that walks GuiEventListener, e.g. Controlify's controller navigation - reaches Compose content the same way it reaches an ordinary AbstractWidget.

ComposeScreen/ComposeContainerScreen rebuild a fresh list of adapters on every children() call, since the LayoutNode tree can change between frames. Vanilla's own ContainerEventHandler.handleTabNavigation looks up the previously-focused GuiEventListener by indexOf in that freshly rebuilt list, so equals/hashCode are keyed on the wrapped node's identity rather than the adapter's - two adapters wrapping the same node must compare equal across separate children() calls, or Tab would never be able to tell "the currently focused thing" apart from "a brand new list entry" and always restart from the beginning.
