Remove all icons and emojis - keep it simple (KISS principle)

Changes:
- Replaced checkmarks with plain text in README.md
- Replaced emoji icons with [OK] in install.sh
- Changed ALE error/warning signs from unicode to ASCII (X and !)
- Removed rocket emoji from QUICKSTART.md
- All output now uses simple ASCII characters

Follows KISS (Keep It Simple, Stupid) principle for better:
- Terminal compatibility
- Accessibility
- Readability in all environments
- No font dependencies
