[frontier] Agent workflows crash on transient LLM errors and lose hours of progress due to lack of durability

Model agent workflows as Temporal state machines with explicit compensation logic and deterministic replay for each LLM call, treating agent steps as durable events

Journey Context:
Simple DAG orchestrators \(Airflow/Celery\) fail when an LLM call rate-limits or hallucinates a tool parameter, leaving the workflow in an undefined state with no recovery path. Temporal \(or similar durable execution engines\) models each agent step as a state machine transition with event sourcing: every LLM call and its response is logged, enabling deterministic replay after crashes. This allows 'exactly-once' execution of side effects \(API calls, database writes\) even when the LLM is flaky, supports long-running human-in-the-loop recovery workflows, and provides compensation logic \(Saga pattern\) for undoing partial work when agent tasks fail irreparably.
