[agent\_craft] Summarizing code context loses critical implementation details needed for accurate patching

Use structured extraction \(AST-based outlines or symbol definitions\) instead of LLM summarization for code. Reserve LLM summarization only for conversational history, not structural code context.

Journey Context:
LLM summarization of code often hallucinates or drops the exact variable names, indentation, or import paths needed to write a working diff. AST extraction preserves the exact symbol names and signatures while reducing token count by 10x. Tradeoff: requires an AST parser tool, but eliminates hallucinated identifiers.
