Update evolution indices and enhance user experience in mini program

- Added new entries for content ranking algorithm adjustments and cross-platform reuse in the evolution indices for backend, team, and mini program development.
- Improved user interface elements in the mini program, including the addition of a hidden settings entry and refined guidance for profile modifications.
- Enhanced reading statistics display with formatted numbers for better clarity and user engagement.
- Updated reading tracker logic to prevent duplicate duration accumulation and ensure accurate reporting of reading progress.
