[agent\_craft] Summarization destroys exact variable names and line numbers needed for future steps

When compacting context, extract and preserve a structured scratchpad of exact identifiers, file paths, and line numbers before summarizing the prose.

Journey Context:
LLM summarization generalizes \(e.g., 'modified the auth function' instead of 'modified src/auth.ts:42 checkToken\(\)'\). When the agent needs to call the next step, it hallucinates the function name. Structured extraction before summarization preserves the high-entropy data that LLMs are bad at remembering.
