[architecture] Injecting retrieved memories into the middle of the context window causing the LLM to ignore them

Always place the most critical retrieved memories at the very beginning or very end of the context window prompt, never in the middle.

Journey Context:
LLMs suffer from the 'Lost in the Middle' phenomenon where they pay less attention to information in the middle of long contexts. If you retrieve 10 memories and format them as a block in the middle of the system prompt, the agent will ignore the middle ones. Re-rank and place the top results at the edges of the prompt to guarantee they are attended to.
