[architecture] Agent fails to use highly relevant memories simply because they were placed in the middle of the injected context prompt

Position the most critical retrieved memories at the very beginning or very end of the context window. Deduplicate and aggressively filter retrieved memories before injection to minimize context length.

Journey Context:
Research shows LLMs disproportionately attend to the beginning and end of the context window, ignoring the middle. If an agent retrieves 10 memories and stuffs them into the prompt, the 5th memory is effectively invisible. Instead of blindly injecting all results, re-rank them, keep only the top K \(where K is small\), and place them at the edges of the prompt template. The tradeoff is potentially dropping a marginally relevant memory, but this is strictly better than it causing a context window distraction.
