[frontier] Agent loses context between tool calls using MCP

Implement MCP Resource subscriptions with server-sent events for live context updates instead of stateless tool calls

Journey Context:
Teams initially treat MCP as a glorified REST wrapper, calling tools statelessly. In production, this causes context loss between multi-step operations \(e.g., editing a file then verifying\). The fix is leveraging the 2025-03-26 spec's Resource subscriptions, where servers push updates to clients, maintaining ambient context without chat-history bloat. Alternatives like polling introduce latency; subscriptions are the only scalable pattern for long-running agent sessions.
