Report #75999

[frontier] Distributed agents losing synchronization on shared tool state causing race conditions in multi-step workflows

Implement MCP resources with listChanged notifications to establish a reactive state bus where agents subscribe to state mutations rather than polling

Journey Context:
Polling creates O\(n\) overhead and stale reads; simple HTTP SSE streams lack acknowledgment guarantees. The subscription pattern uses JSON-RPC notifications to push state deltas, enabling event-sourced agent topologies. Tradeoff: increases coupling to MCP server availability, but eliminates consensus complexity in distributed agent meshes.
