[agent\_craft] Summarizing past agent steps destroys exact tool call IDs and API state

Use structured compaction. Keep exact JSON payloads of the last N tool calls, but summarize the human-readable reasoning. Extract key variables into a structured scratchpad.

Journey Context:
When an agent compacts context to stay in-window, naive text summarization makes it impossible to resume API calls or reference exact file paths/line numbers. State tracking requires exactness. A hybrid approach—summarizing the prose but keeping the exact JSON—preserves both semantic meaning and execution state, preventing the agent from hallucinating previous tool outputs.
