Report #58611

[frontier] Long-running agent workflows failing silently on pod restart losing 30min\+ progress

Replace async/await agent orchestration with Temporal workflows; deterministically checkpoint agent state after each LLM call and tool execution using workflow replay for fault tolerance across pod restarts and retries

Journey Context:
Kubernetes preemption kills agent pods running long tasks. Simple database checkpointing fails because LLM calls are non-deterministic \(temperature, randomness\). Durable execution engines like Temporal externalize non-deterministic operations through activities and maintain workflow state durably, enabling automatic replay and recovery without losing progress
