[agent\_craft] Rolling summarization of agent steps loses exact variable names and file paths, causing hallucinated references

Use structured summarization templates \(e.g., JSON schemas\) that mandate preserving exact identifiers, error codes, and file paths, rather than free-text summarization.

Journey Context:
When an agent summarizes 'Fixed the bug in the auth module', it loses the fact that it was \`src/v2/auth\_handler.py::validate\_token\`. Later, it might guess the path. Structured compaction forces the LLM to retain high-signal entities while discarding conversational fluff, ensuring downstream steps can reliably reference the exact state.
