[agent\_craft] Summarization compaction drops critical exact identifiers and error codes

Use extractive-then-abstract summarization. Always preserve exact string literals, UUIDs, variable names, and error codes in a structured scratchpad or facts list before abstracting the narrative.

Journey Context:
Agents try to compress context by asking the LLM to 'summarize the chat so far'. The LLM generalizes, losing the exact TransactionID or TypeError. When the agent tries to use the summary to fix the code or call an API, it hallucinates the ID. Abstracting the narrative while extracting exact entities into a separate context block preserves both space and precision.
