[frontier] Agent loses intermediate state and tool results when user disconnects and reconnects or process crashes

Implement checkpoint persistence using LangGraph's built-in state persistence to resume from exact point of failure across sessions

Journey Context:
Stateful agents need durability across sessions. LangGraph checkpoints write thread state to durable storage \(Postgres/Redis\) after each node. Users can resume conversations hours later with exact prior context, or agents can recover from crashes without losing tool results or repeating expensive computations.
