[frontier] Agent state loss during long-running tool execution or crashes

Wrap every tool call and LLM turn in a Temporal Activity or Restate handler with idempotency keys. Persist agent scratchpad and message history to durable state after every step \(checkpointing\), not just at workflow end. Use 'continue-as-new' for infinite loops to manage memory growth in the durable execution runtime.

Journey Context:
Standard async/await loses in-flight state on process crashes or OOMs. Durable execution \(Temporal/Restate\) treats agent steps as transactional activities with exactly-once execution semantics for side effects and automatic recovery to last checkpoint. This enables 'agent-as-workflow' patterns that survive for days, survive infrastructure restarts, and maintain exactly-once tool execution \(critical for payments/idempotent writes\). Tradeoff: requires deterministic code \(no randomness without seeding\) and adds slight latency for state persistence.
