[frontier] How to implement real-time updates in MCP beyond one-shot tool calls

Use MCP Resource Subscriptions \(2025-03-26 spec\) to establish long-lived connections where servers push updates to clients, rather than polling tools.

Journey Context:
Polling tools creates latency and misses state changes. REST-style tool calls assume request/response. Resources with subscriptions allow agents to react to external state changes \(file edits, DB updates\) in real-time. Tradeoff: increases connection complexity but enables reactive agent behaviors.
