Fix Yazi shell integration and enhance Kitty configuration

**Yazi Integration Fixes:**
- Fixed y() function in .zshrc to prevent shell exit when quitting Yazi
- Updated kitty-yazi.sh script to use AppleScript for proper tab creation
- Script now focuses existing Kitty window and creates new tab instead of new window

**Kitty Configuration Enhancements:**
- Added advanced font rendering with ligature support
- Improved cursor animations and visual effects
- Enhanced tab bar with powerline styling and fade effects
- Added background blur and better transparency handling
- Optimized performance settings (rendering delays, scrolling)
- Added comprehensive keyboard shortcuts for window/tab management
- Improved URL handling and text selection features
- Added notification system for long-running commands
