[agent\_craft] Rolling narrative summaries of past steps lose the exact error messages or variable states needed for debugging

Replace narrative summarization with structured extraction. Compact past turns into a structured list of Key Facts, Exact Error Strings, and Failed Approaches rather than a paragraph of prose.

Journey Context:
Narrative summaries \(I tried to fix the bug but it failed\) are useless for debugging. You need the exact error string \(ModuleNotFoundError: No module named 'foo'\). Structured extraction preserves high-signal data \(exact strings, variable states\) while narrative summarization preserves low-signal data and discards the exact tokens needed for deterministic fixes.
