[architecture] Multi-hop reasoning collapses because each retrieval step overwrites the previous evidence

Keep a persistent reasoning scratchpad across hops; append retrieved facts, synthesize before answering, and never replace the full context each turn.

Journey Context:
Iterative retrieval needs accumulated evidence. If the agent's working memory is reset to only the latest retrieval, earlier facts vanish. ReAct/chain-of-thought agents maintain a trace of prior thoughts and observations precisely to prevent this. Design memory so earlier hops remain addressable while new evidence is added.
