refactor: enhance RouteOpts and Route class generics for improved type safety

- Updated RouteOpts to accept an additional generic parameter for metadata type.
- Modified Route class to utilize the new generic parameter for metadata.
- Adjusted the run method in QueryRouterServer for consistent type definitions.
- Improved getList method in QueryRouter to allow filtering of routes.
