[frontier] Distributed agent workflows leave partial state updates when one agent fails, causing data inconsistency across the fleet

Implement the Saga pattern for multi-agent operations: decompose long-running tasks into a sequence of local transactions, where each agent completes its work and emits a domain event. If a subsequent step fails, execute compensating transactions \(rollback operations\) for each completed step to maintain eventual consistency. Use a Saga Orchestrator \(central coordinator\) for complex workflows or Choreography \(event bus\) for loose coupling, with timeouts and idempotency keys on all operations.

Journey Context:
In microservices, sagas handle distributed transactions without 2PC \(two-phase commit\). Agent fleets have the same problem: Agent A reserves inventory, Agent B processes payment, Agent C fails to ship. Without compensation, inventory stays reserved. The saga pattern defines compensating actions for each step \(e.g., 'release inventory' for the reserve step\). This is emerging as agent workflows become long-running and cross-organizational. Alternatives: 2PC \(too blocking for agents\), simple retry \(leaves inconsistency\), distributed locks \(deadlock prone\).
