[frontier] Cannot resume agent execution from middle of complex workflow after human interruption

Implement deterministic checkpointing of agent state graph after every node; serialize full state \(messages, config, next node\) to durable store to allow resumption from any step.

Journey Context:
Traditional agent loops lose all progress if interrupted for human approval or system crash. LangGraph and similar frameworks now support deterministic checkpointing—serializing the full state \(messages, configuration, next node\) after every step to a durable store \(Postgres, Redis\). This enables 'human-in-the-loop' patterns where execution pauses for approval, then resumes from exact state without re-execution. This is critical for production agents handling sensitive operations where human oversight is required mid-workflow, ensuring no progress is lost and audits are complete.
