[architecture] Agent ignores relevant memories injected into the middle of the prompt context

Place the highest-priority retrieved memories at the very beginning or the very end of the prompt context. Avoid placing critical instructions or memories in the middle of large context blocks.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon where they pay attention to the start and end of the context but ignore the middle. When injecting memories, naive concatenation scatters critical facts. The tradeoff is that reordering memories might disrupt narrative flow, but prioritizing recall accuracy over narrative is essential for agent reliability.
