[frontier] How to push real-time context updates to AI agents without polling MCP servers

Implement MCP Resource Subscriptions using the roots and resources subscription primitives to push context diffs to agents, eliminating polling loops and reducing latency by 10x in multi-agent chains.

Journey Context:
Teams currently poll MCP servers for resource updates, causing cascading latency in multi-agent chains. The MCP spec supports subscriptions \(roots and resources\), but most implementations ignore them. The shift is from pull-based to reactive push architectures, similar to GraphQL subscriptions but for agent context. Tradeoff: requires handling backpressure and reconnection logic, but eliminates N\+1 query problems in agent swarms.
