[agent\_craft] Agent truncates oldest messages when hitting token limits, losing critical early instructions or task state

Implement a rolling summarization \(compaction\) strategy for older turns, but always preserve the original system prompt and the most recent N turns verbatim.

Journey Context:
Simple FIFO truncation breaks multi-step agents because they forget the original goal or constraints established in early turns. Summarization preserves semantic intent while freeing tokens. However, summarizing the system prompt or the immediate last few steps causes hallucination or task drift, so those must remain intact.
