[architecture] Retries in multi-agent orchestration cause duplicate side effects

Attach idempotency keys to inter-agent task payloads and enforce deduplication at the receiving agent's state store or tool execution layer before committing side effects.

Journey Context:
Distributed systems principles apply to multi-agent systems. If an orchestrator agent dispatches a task to a worker agent and times out, it doesn't know if the worker executed it. Naive retries lead to duplicate DB writes or API calls. Passing an idempotency\_key allows the worker agent to check if the exact request was already processed. Tradeoff: requires stateful tracking on the worker side, but essential for any mutating operations.
