Update configs, social links, and about page content

Refactored Hugo workflow to simplify version handling. Improved .gitignore for better coverage. Removed unused social icons and verification file. Updated site configs for base URL, markup, menu (added GitLab, removed YouTube/X), and comment system. Enhanced about page with current work info and clarified blog purpose.
