[architecture] Injecting retrieved memories into the middle of the prompt, causing the agent to ignore them

Place the highest-relevance memories at the very beginning and end of the context window, or use a separate system prompt block for memory injection.

Journey Context:
LLMs suffer heavily from the 'lost in the middle' phenomenon. If you retrieve 20 memories and drop them in the middle of the prompt between the system prompt and the user query, the ones in the center are effectively invisible to the model. Reordering retrieved chunks so the highest scores are at the edges maximizes recall, even if it breaks strict chronological order.
