Report #25378

[frontier] Agent crashes lose hours of progress and require full restart

Implement state checkpointing after each tool execution node with persistent storage \(Postgres/SQLite\) to enable resume from exact failure point

Journey Context:
Long-running research agents or coding agents need resumability. LangGraph's persistence layer saves thread state \(checkpoints\) after each superstep to a database. This enables time-travel debugging \(replaying from arbitrary points\) and human-in-the-loop approval gates. Without deterministic checkpointing, production agents are too risky for long-horizon tasks because any API timeout or crash destroys progress.
