[architecture] Duplicate side effects when orchestrator retries a failed agent execution

Assign idempotency keys to inter-agent handoffs and require downstream agents to check/write a deduplication record before executing irreversible side effects.

Journey Context:
Distributed systems principles are often forgotten in LLM architectures. If an agent makes an API call and the network drops, the orchestrator doesn't know if it succeeded. Without idempotency keys, retries cause duplicate DB writes, emails, or payments. The tradeoff is added latency for the dedup check, but it is strictly required for state-mutating agents.
