* Subscribe to the router's state store with optional selection and

* - `select`: Project the full router state to a derived slice
* - `structuralSharing`: Replace-equal semantics for stable references
* - `router`: Read state from a specific router instance instead of context
*
* @returns The selected router state (or the full state by default).
