Singleton store that persists the last [`PageContextSnapshot`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/pagecontextsnapshot) per SignalR connection ID across DI scope boundaries. SignalR creates a new DI scope for every hub method invocation, so the Scoped [`IMentorPageContext`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-interfaces/imentorpagecontext) resolved in `UpdatePageContext` is a different instance from the one resolved in `SendMessage`. This store bridges the gap: `UpdatePageContext` writes here; `SendMessage` reads and applies before the orchestrator runs.
