[architecture] Duplicate side effects when agent handoffs timeout and retry

Assign a globally unique idempotency key at the orchestrator level and pass it down through the agent chain. Tools and external API calls must check this key before mutating state.

Journey Context:
Network calls between agents or to tools can fail or timeout. If an orchestrator dispatches a task to Agent A, and the response is lost, the orchestrator retries. Without an idempotency key, Agent A executes the side effect twice. LLMs are stateless, so state management must be external. Tradeoff: requires external state store for keys, but essential for safe retries.
