[frontier] How to avoid polling RAG databases in real-time agent workflows

Implement MCP Resource Subscriptions with listChanged notifications to push context updates only when data changes, eliminating polling latency and redundant token usage.

Journey Context:
Traditional RAG requires periodic polling or manual refresh, causing stale context or excessive latency. MCP Resources with subscriptions allow the server to notify the agent of changes via JSON-RPC notifications. Alternative is HTTP SSE or custom WebSocket implementations, but MCP standardizes the protocol across servers. This is correct because it decouples context freshness from agent loop timing and reduces token waste on unchanged data, which is critical for long-running agents.
