[frontier] Partial failures in multi-step agent workflows leave systems in inconsistent states

Apply the Saga pattern \(compensating transactions\) to agent workflows; define explicit undo operations for each step, orchestrate via durable execution, and automatically execute compensation chain on any step failure.

Journey Context:
Agent workflows perform sequences of external actions: reserve inventory, process payment, send confirmation. If the payment step fails after inventory was reserved, the reservation remains orphaned—state inconsistency. Traditional distributed transactions \(2PC\) don't work across LLM calls and external APIs. The Saga pattern \(established in microservices, now applied to agents\) solves this: each step has a 'compensating transaction' \(undo\). If step N fails, execute compensations for steps N-1 through 1 \(reverse order\). This requires durable execution \(surviving crashes mid-compensation\) and explicit undo logic for each tool. The frontier aspect is applying this to non-deterministic LLM steps where 'undo' might mean 'refund payment' or 'notify cancellation.' This transforms fragile agent scripts into reliable business processes with ACID-like semantics via compensation.
