[frontier] Agent losing in-progress state on container restart or migration

Deploy agent with sidecar state manager: agent process is stateless, all context/checkpoints written to sidecar \(Redis/etcd\) via MCP or HTTP, on restart new instance hydrates from sidecar, enables zero-downtime updates

Journey Context:
Stateful agents \(maintaining conversation history in memory\) cannot be scaled horizontally or updated without downtime. When the container crashes, hours of work are lost. The sidecar pattern \(from Kubernetes/microservices\) separates the application logic from state management. The agent process itself is stateless; it serializes its full context \(memory, plan, tool results\) to a sidecar service \(Redis, etcd, or a custom MCP state server\) after every significant step. On startup, it hydrates from this store. This enables blue-green deployments \(new version starts, loads state, takes over\) and crash recovery. The tradeoff is latency \(serialization cost\) and complexity \(handling schema migrations in stored state\), but it is essential for production-grade agent reliability.
