Report #95280

[architecture] Retrying a failed agent step causes duplicate side effects

Assign a unique idempotency key \(e.g., workflow\_id \+ step\_id\) to each agent execution and pass it to tool calls, ensuring tools reject duplicate executions.

Journey Context:
LLMs are non-deterministic and network calls fail; retries are inevitable. Without idempotency keys at the orchestration level, a timeout on Agent B's tool call might lead the orchestrator to retry, causing duplicate real-world actions like sending emails twice. The key makes the operation safely retryable.
