Report #69144

[frontier] MCP tools polling causing high latency for real-time data feeds

Use MCP Resource Subscriptions: implement \`subscribe\` capability on resources and push updates via \`notifications/resources/updated\` rather than polling tool calls.

Journey Context:
Polling tools for live data \(stock prices, logs\) adds 500ms\+ latency per check. The MCP spec supports Resource Subscriptions where the server pushes updates when content changes. This shifts from request-response to pub-sub, essential for reactive agents that need live state without token-wasting polling loops.
