[agent\_craft] Summarizing the whole chat throws away the constraints that matter

Replace prose summarization with schema-driven compaction: after each turn extract open TODOs, unresolved decisions, hard invariants, and key facts into a structured memory block, then carry that block forward instead of a narrative summary.

Journey Context:
A plain summary preserves the gist but silently drops negative constraints, exact values, and vetoed alternatives. Structured extraction forces the agent to decide what is actionable and keeps the next turn's context machine-readable. This is the same reason LangGraph separates short-term checkpoints \(graph state\) from durable stores: state belongs in the window, but it should be compact and typed.
