Report #57129

[frontier] Agent polling for external state changes causes latency and unnecessary token consumption

Use MCP Resource Subscriptions to push state changes to agents only when data mutates, restructuring agent loops from pull to push

Journey Context:
Traditional agents poll APIs or databases in a loop, wasting tokens on unchanged state and introducing latency. MCP's subscription model \(spec v1.0\+\) allows servers to push updates only when resources change. This requires restructuring agent loops from 'pull' to 'push' event handlers, but eliminates latency and reduces context window pollution from stale data checks. The tradeoff is increased complexity in handling out-of-order updates and maintaining subscription liveness.
