[frontier] Agents polling external systems inefficiently or missing state changes

Adopt MCP Resource Subscriptions to push state changes to agents via server-sent events rather than polling tools.

Journey Context:
Standard tool-calling assumes a request-response model where the agent must invoke a tool to check state. This creates either high latency \(waiting for next turn\) or wasted tokens \(repeated polling calls\). MCP Resources with subscriptions allow servers to push updates when state changes \(e.g., file modified, database updated\). The agent registers a subscription, then blocks or yields until notified. Tradeoff: requires maintaining persistent connections and handling backpressure. Polling is simpler but fails for real-time coordination where sub-second reaction matters.
