[frontier] Agent context sync failures in multi-agent systems using polling loops

Implement MCP Resource Subscriptions to push context updates between agents instead of polling

Journey Context:
Teams currently use polling loops or message queues for inter-agent sync, causing 500ms\+ latency and race conditions. MCP Resources have a subscribe capability that allows one agent to subscribe to another's resource URI, receiving JSON-RPC notifications on changes. This eliminates polling overhead and provides exactly-once delivery semantics through JSON-RPC 2.0. Unlike naive WebSockets, this integrates with MCP's capability negotiation and access control. The pattern is emerging in Claude Desktop's multi-agent experiments but not yet in SDK tutorials.
