This commit modifies various metadata and canonical URLs in the SurfSense application to ensure consistency by using "https://www.surfsense.com" instead of "https://surfsense.com". Changes were made in layout files, blog posts, and SEO components to reflect this update.
- Revised metadata titles and descriptions across multiple pages to better reflect the open-source and privacy-focused nature of SurfSense.
- Enhanced user engagement by simplifying titles for the free AI chat feature and individual model pages.
