[synthesis] Cross-step state drift where agent hallucinates a slightly different variable value from an earlier step

Implement an explicit, structured state object \(a 'scratchpad'\) that the agent reads from and writes to at every step, rather than relying on the conversational context to hold variables.

Journey Context:
LLMs are stateless and have imperfect recall over long contexts. Synthesis of AutoGen's state management and LLM positional encoding reveals 'Positional State Drift.' As a conversation grows, the positional encoding of early variables changes, making them harder to recall exactly. The chat history is a lossy medium for variable storage. Externalizing state to a structured scratchpad guarantees exact recall.
