fix: correct table of contents anchor links in README.md

Updated all TOC links to match GitHub's anchor generation for headers with emojis.
Headers like "## 🎯 Overview" generate anchors like "#-overview" (with leading dash).

Changes:
- Updated 12 TOC links from #section to #-section format
- Links now properly navigate to their respective sections
