refactor: simplify to single version with beautiful README

- Removed old versions (install-advanced.sh, install-advanced-v2.sh)
- Renamed install-advanced-v2.sh → install.sh (main installer)
- Created beautiful new README.md with:
  - Improved visual design with tables and badges
  - Collapsible sections for better navigation
  - Enhanced documentation structure
  - Better emoji usage and formatting
  - Clearer installation instructions
  - Comprehensive feature showcase

Breaking Changes:
- Installation URL changed to: install.sh (was: install-advanced.sh)
- Single unified version (v2.1.0)
