[agent\_craft] Summarizing past tool calls and outputs loses critical state details needed for later steps

Use structured compaction: keep the exact signatures and return types of previous tool calls, but summarize the narrative reasoning. Never summarize code diffs or exact error messages; compress the surrounding text instead.

Journey Context:
Agents often fail mid-task because a summarizer truncated a crucial variable name or error code from a previous step to save tokens. Generic LLM summarization treats all text equally. For coding agents, the exact code state and error outputs are high-entropy, while the 'I will now try to...' reasoning is low-entropy. Compaction must be asymmetric.
