Report #24638

[frontier] Agent polling for state changes causing high latency and token waste

Use MCP Resource Templates with subscriptions \(listChanged:true\) to push updates to agents instead of polling tools

Journey Context:
Teams default to tool-calling patterns for state checks, causing n\+1 queries and high token consumption. MCP Resources \(2024-11-05 spec\) allow servers to notify clients of changes via subscriptions. This shifts from pull to push, critical for multi-agent shared state and real-time collaboration. Tradeoff: requires server-side pub/sub capability and connection persistence.
