End-of-Day Reflection Prompts for Session Context

Add optional EOD prompts that ask reflection questions (e.g., "What did you work on today?", "Biggest wins?", "Key challenges?"). User answers feed into the AI categorization engine, giving Rize context beyond URLs/apps. Helps bridge the gap between what ran vs. what actually got accomplished. Could trigger at a user-defined EOD time or be manually initiated. Answers stored per day for richer session understanding and more accurate auto-categorization.
