[architecture] Saving Raw Chat History as Agent State

Serialize the agent's state as a structured object \(e.g., JSON schema of current variables, task queue, and a summary of past actions\) rather than a flat list of messages. Restore by injecting this structured state into the system prompt.

Journey Context:
Chat history is a poor proxy for agent state. An agent's 'memory' of its current task is often buried in thousands of tokens of tool I/O. When resuming a paused agent, re-feeding this history wastes tokens and risks hitting limits. By maintaining a structured 'scratchpad' or state object that is updated via tool calls, you can pause the agent, serialize just the state object to a database, and reconstruct the agent in a new context window with a single, dense system prompt, enabling true cross-session persistence.
