[frontier] Agent loses state consistency across tool calls and sessions when using MCP

Implement bidirectional state synchronization using MCP's Resource primitives with subscription patterns rather than just stateless tool calling; treat state as versioned CRDT-like resources that sync automatically

Journey Context:
Teams initially adopt MCP for tool calling but hit consistency issues when agents need complex state across sessions. The naive approach stores state in context windows or external DBs with manual sync, causing drift when multiple agents interact with the same entities. The robust pattern uses MCP's Resources \(not just Tools\) to expose state as addressable, subscribable entities. Resources support subscriptions for real-time sync and versioning for conflict resolution, similar to local-first CRDTs but mediated through the protocol. This prevents the 'lost update' problem when agents concurrently modify shared state.
