[agent\_craft] Agent forgets instructions or early context when conversation history grows long

Put critical instructions at the very beginning or very end of the context window; use periodic re-injection of the primary directive in system prompts or intermediate steps.

Journey Context:
LLMs suffer from 'lost in the middle' degradation where attention drops for information in the middle of long contexts. Agents often append tool results to the middle/end, pushing the original system prompt further away. Re-injecting the core goal or moving it to the latest turn ensures high attention. Tradeoff: consumes tokens, but prevents hallucination.
