Report #11894

[architecture] Agent loses its current plan and progress when a long-running session crashes or is interrupted

Externalize agent state \(scratchpad, current plan, memory pointers\) to a persistent checkpoint database at every state transition, not just at the end of the task.

Journey Context:
Developers often rely on in-process variables to hold the agent's working memory or plan. If the process halts, the agent must start from scratch. By treating the agent's execution as a state machine and persisting the state after every tool call or LLM response \(checkpoints\), the agent can resume exactly where it left off, enabling fault tolerance and human-in-the-loop interruptions.
