Decorates [`IMentorStateService`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-interfaces/imentorstateservice) to forward every AI event to the connected SignalR client via `Clients.Client(connectionId).SendAsync(...)`. Also bridges the [`IMentorPageContext`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-interfaces/imentorpagecontext) by applying page context snapshots received from the remote client before each AI call.
