Creates a new `GenerateCosmoRouterConfig` function to build and serialize a Cosmo Router configuration from subgraphs. Implements PubSub mechanism for managing schema updates, allowing subscription to updates. Adds Subscription resolver and updates existing structures to accommodate new functionalities. This enhances the system's capabilities for dynamic updates and configuration management.
