Bug Description

According to mypy None of the subclasses of BaseRouter correctly implement the abstractmethod add_route.

class BaseRouter(ABC):
    @abstractmethod
    def add_route(*args) -> Union[Callable, CoroutineType, WebSocket]: ...

vs

class Router(BaseRouter):
...
    def add_route(
        self,
        route_type: HttpMethod,
        endpoint: str,
        handler: Callable,
        is_const: bool,
        exception_handler: Optional[Callable],
        injected_dependencies: dict,
    ) -> Union[Callable, CoroutineType]:

vs

class MiddlewareRouter(BaseRouter):
...
    def add_route(
        self,
        middleware_type: MiddlewareType,
        endpoint: str,
        handler: Callable,
        injected_dependencies: dict,
    ) -> Callable:

vs

class WebSocketRouter(BaseRouter):
...
    def add_route(self, endpoint: str, web_socket: WebSocket) -> None:
        self.routes[endpoint] = web_socket

The mypy errors are:

Signature of "add_route" incompatible with supertype "BaseRouter"
...
     Superclass:
         def add_route(*args: BaseRouter) -> Callable[..., Any] | CoroutineType[Any, Any, Any] | WebSocket
     Subclass:
         def add_route(self, route_type: HttpMethod, endpoint: str, handler: Callable[..., Any], is_const: bool, exception_handler: Callable[..., Any] | None, injected_dependencies: dict[Any, Any]) -> Callable[..., Any] | CoroutineType[Any, Any, Any]
...
     Superclass:
         def add_route(*args: BaseRouter) -> Callable[..., Any] | CoroutineType[Any, Any, Any] | WebSocket
     Subclass:
         def add_route(self, middleware_type: MiddlewareType, endpoint: str, handler: Callable[..., Any], injected_dependencies: dict[Any, Any]) -> Callable[..., Any]
...
     Superclass:
         def add_route(*args: BaseRouter) -> Callable[..., Any] | CoroutineType[Any, Any, Any] | WebSocket
     Subclass:
         def add_route(self, endpoint: str, web_socket: WebSocket) -> None

I can't find any use of BaseRouter in the codebase.

Options:

1. fix the signatures in the 3 subclasses to match BaseRouter
2. remove the abstractmethod add_route from BaseRouter (all tests still pass)
3. remove the whole BaseRouter abstract class and make the others just classes (all tests still pass)

Steps to Reproduce

1. run mypy 1.13 on the codebase
