[architecture] Losing agent execution state and memory context on pause/restart

Serialize the agent's scratchpad, current plan, and working memory into a structured JSON snapshot before terminating, and reconstruct the context window strictly from this snapshot on initialization.

Journey Context:
When an agent pauses or crashes, developers often only persist the vector store \(long-term memory\) but lose the short-term working memory \(the current plan, the last tool output\). On restart, the agent forgets what it was doing. The tradeoff is the complexity of a strict state machine vs. the unreliability of an agent trying to infer where it left off. Explicit checkpointing of working memory is mandatory for reliable cross-session persistence.
