Builds a KeyRouter from stone.keyRouting.definitions (explicit key-routes) and
stone.keyRouting.handlers (classes with @OnKey methods, scanned), resolving classes/factories
with dependency injection, then binds it as keyRouter. The KeyRoutingEventHandler
dispatches through it.
Wires the light key-router into the container.
