Report #14436

[agent\_craft] Summarizing conversation history loses critical variable names and IDs needed for code generation

Use extractive summarization for code/identifiers \(keeping exact tokens\) and abstractive summarization only for natural language intent. Maintain a separate scratchpad of exact names/types.

Journey Context:
LLMs naturally abstract when summarizing \('the user wants to update the database connection'\). But coding requires exact symbol names \(\`db\_conn\_pool\_v2\`\). Abstractive summarization hallucinates or generalizes these, leading to NameErrors later. Dual-track summarization preserves exact syntax while compressing intent.
