Report #31295

[frontier] Agent not receiving real-time updates from external data sources

Implement MCP \`resources/subscribe\` to establish push-based subscriptions rather than polling endpoints

Journey Context:
Agents often poll APIs repeatedly, wasting tokens and causing latency. The MCP protocol defines a \`resources/subscribe\` method that allows servers to push updates when state changes. This requires maintaining a long-lived connection and handling \`notifications/resources/updated\` messages. Alternative is polling \`resources/read\`, but this misses updates between polls and consumes unnecessary context window. The subscription pattern is essential for reactive agents that must respond to external events in real-time.
