Now that handleRegistration accepts WebSocket instead of any, the as any cast on socket when calling this method in handleWSConnection (line 222) is redundant and should be removed to maintain clean type safety.

Now that clearPendingForSocket accepts WebSocket instead of any, the as any cast on socket when calling this method in handleWSConnection (line 241) is redundant and should be removed. Additionally, consider updating the requesterSocket property in the SocketPendingRelayRequest interface (line 63) to WebSocket to fully propagate this type safety improvement.
