- Fix double ### headers in CHANGELOG sections
- Update date format to Keep a Changelog standard [version] - date
- Reorganize sections in proper order (Added, Changed, Fixed, Documentation)
- Update .versionrc.json to remove ### from section names (standard-version adds them automatically)
- Ensure Pages deployment and troubleshooting are properly documented in Fixed section
