⚠️ Breaking Changes

• Minimum PHP version increased from 8.1 to 8.2
• Removed markrogoyski/math-php dependency - replaced with pure PHP implementation

✨ Performance & Architecture Improvements

CUID Generation:

• Cleaner, more maintainable implementation

Base Conversion:

• New Utils class with optimized base36 conversion algorithm
• Uses intermediate large base (100 million) for efficient arithmetic
• Pure PHP implementation, zero external dependencies
• GMP still recommended for optimal performance
