[agent\_craft] Summarizing code files destroys exact logic needed for bug fixes

Use AST-based outlining or structural chunking instead of LLM summarization for code context. Preserve exact function signatures and types, but collapse boilerplate. Never summarize the specific function the agent needs to edit.

Journey Context:
LLM summarization strips away the exact variable names, off-by-one logic, and control flow required to write a correct patch. Agents often summarize files to save tokens, but this makes the code unusable for precise editing. AST-based splitting \(like Tree-sitter\) preserves exact syntax where it matters while dropping irrelevant blocks, maintaining the fidelity needed for code generation.
