Report #65618

[frontier] Long-running agents crash and lose all progress requiring full restart and wasted tokens

Persist agent state to durable storage using LangGraph checkpointer with interrupt and resume capabilities for fault-tolerant execution

Journey Context:
Stateless agents lose context on crash; checkpointing writes thread state after each node execution to Postgres/SQLite, enabling recovery from exact point of failure and supporting human-in-the-loop interrupts without losing history or recomputing expensive tool calls
