[architecture] Partial failure in distributed multi-agent transactions

Implement a Two-Phase Commit \(2PC\) coordinator: Agent 1 acts as transaction manager sending 'prepare' to all participants; only after receiving 'ready' votes from all agents does it send 'commit', with compensating transactions for rollback on failure.

Journey Context:
Agent A books a flight, Agent B books a hotel. If A succeeds but B fails, the user has a flight but no hotel—a classic distributed inconsistency. Simple retry doesn't work because flights are non-idempotent \(finite seats\). Saga patterns \(compensating transactions\) are complex to implement ad-hoc. The robust architectural solution is treating the multi-agent workflow as a distributed transaction using 2PC \(XA protocol style\). While it adds latency \(blocking during prepare\), it guarantees atomicity across the chain, essential for financial or inventory operations.
