[agent\_craft] Important context ignored when placed at start or end of long prompts

Place the most critical instructions and context in the middle-third of the prompt, surrounded by secondary information, to exploit the 'lost in the middle' attention pattern.

Journey Context:
Common practice puts system instructions at the very beginning and the most recent user query at the end. However, research shows transformer attention mechanisms exhibit U-shaped recall over long contexts. The beginning and end get high attention, while the middle suffers. By placing critical content slightly off-center in the middle, it receives more relative attention than at the extremes. This is counter-intuitive to sequential reading order but essential for long-context retrieval.
