Report #74978

[frontier] Agent polling MCP resources causes high latency and misses real-time updates in event-driven workflows

Implement MCP resource subscriptions to receive server-sent push updates when resource content changes, eliminating polling loops

Journey Context:
Current agent implementations poll MCP resources \(files, databases\) on every iteration, creating 500ms\+ latency and race conditions. The 2025 MCP specification added resource subscriptions allowing servers to push updates via JSON-RPC notifications. This shifts agents from polling loops to reactive event-driven architectures, essential for real-time agents monitoring file systems or APIs.
