Context Window Overflow Causes Amazon Q to Lose Current Prompt

Currently, when Amazon Q's context window overflows, it summarizes the conversation history. However, this process appears to include the most recent user prompt in the summarization, causing Q to lose focus on the specific question and respond with generic information that broadly applies to the entire context rather than addressing the immediate query.

**Desired Behavior**:
Amazon Q should preserve the most recent user prompt separately from the summarized context, ensuring it can provide a focused response to the current question after the summarization occurs.
