Report #90035

[frontier] Agent loses state and context on serverless cold starts or crashes mid-task

Persist agent state to Cloudflare Durable Objects with WebSocket hibernation API for reliable long-running execution

Journey Context:
Serverless functions lose memory on cold starts, breaking multi-step agent workflows. Durable Objects provide singleton instances with persistent storage and WebSocket support. Using hibernation APIs, agents can sleep without billing CPU, then resume exactly where they left off. Critical for reliable production agents.
