Report #97005

[architecture] Retrying a failed agent step causes duplicate side effects across the multi-agent chain

Assign a deterministic idempotency key derived from the parent run ID and step index to the payload passed between agents; enforce idempotency at the tool and API level.

Journey Context:
In a multi-agent loop, if Agent C fails and the orchestrator retries from Agent B, B might generate a slightly different payload, but the intent is the same. Without idempotency keys, the external side-effects of B's tools \(like sending an email or writing to a DB\) are repeated. Deriving the key from the run context ensures retries hit the same external state safely.
