[frontier] Long conversation history exceeds context limits while losing critical early details

Use retrospective summarization: after each turn, generate a 'delta summary' of what changed, maintaining a hierarchical memory tree rather than linear history

Journey Context:
Simple truncation or 'keep last N messages' loses crucial early context \(like user preferences\). Full conversation summarization is expensive. Frontier approach: maintain a tree where leaf nodes are actual messages, but after each turn, generate a compressed 'retrospective' node that captures the delta. Older leaf nodes can be pruned, keeping the tree compact. This is distinct from RAG—it's about compressing the agent's own history, not external docs. Enables hour-long sessions without context loss.
