[agent\_craft] Agent ignores crucial instructions placed in the middle of a long context window

Place the most critical instructions and the most recent retrieved context at the very beginning and the very end of the prompt, avoiding the 'middle' of the context block.

Journey Context:
Research shows LLMs suffer from the 'lost in the middle' effect, where attention is highest at the start and end of the context. If you put a crucial constraint in the middle of a 50k token prompt, it will likely be ignored. Restructuring the prompt to put constraints at the top and immediate action items at the bottom maximizes adherence.
