create
Builds a Store of ModelState from a routing block. Each model's starting value comes from its RoutingBuilder.model declaration; there is no INIT-action fan-out. Dispatch routes by the exact leaf class of the action.
Parameters
optional store enhancer (e.g. applyMiddleware), passed straight to createStore.
when true, throws if a handler returns a new but structurally-equal model instance (a wasteful no-op write that would fire subscribers spuriously).
optional OnWrite observer for tracing/conflict detection.
optional restored/persisted models overlaid onto the declared defaults at construction (its key set must be a subset of the declared models). Use to rehydrate state synchronously instead of dispatching after first render.
the routing configuration: model and handler registrations applied to a RoutingBuilder.
