[frontier] Naive RAG is too slow and stale for real-time agent data needs

Replace vector RAG with MCP Resource subscriptions, where agents receive real-time updates via server-sent events or similar, maintaining a live data cache rather than querying static chunks

Journey Context:
Traditional RAG involves chunking, embedding, and retrieving—a batch process that creates stale snapshots. Agents in production need live data \(stock prices, ticket statuses\). The frontier pattern is using MCP Resources with subscriptions. Instead of a vector search, the agent subscribes to a resource URI; the MCP server pushes updates when data changes. This turns data access into a reactive stream rather than a query-response cycle. The agent maintains a local cache of subscribed resources, invalidated by server pushes. This eliminates the 'embedding delay' and allows for complex, structured data \(not just text chunks\) to be passed directly from source systems to agents in real-time.
