[agent\_craft] Context compaction loses task progress and decision rationale, causing agents to repeat or contradict earlier work

When compacting, always preserve a structured task-state block containing: \(1\) Original user request verbatim. \(2\) Completed steps with outcomes. \(3\) Pending steps. \(4\) Key decisions made and their rationale, e.g., 'Chose SQLite over PostgreSQL because this is a local-only tool.' \(5\) Exact identifiers needed for next steps. Place this block at the start of the compacted context.

Journey Context:
Naive compaction — asking the LLM to 'summarize the conversation so far' — produces a narrative summary that is readable but operationally useless. The agent loses track of what it has already done, leading to repeated work; what decisions it made, leading to contradictions; and what it was about to do next, leading to task abandonment. The fix is to treat compaction as a state serialization problem, not a summarization problem. The compacted context should read like a handoff document for a new team member: here is what we are doing, here is where we are, here is what to do next, and here are the exact things you need to know to do it. Free-form summarization destroys this operational structure.
