🎉 Release v0.18.0

✨ Added

• HuxWCAG Utility: New shared WCAG contrast calculation utilities (HuxWCAG class)
  • Centralized WCAG 2.1 compliant contrast ratio calculations
  • Public API for developers to use in custom components
  • Proper gamma correction and ITU-R BT.709 coefficients for accurate calculations
  • Exported from main library for easy access
  • Helper methods: getContrastingTextColor(), calculateContrastRatio(), getRelativeLuminance(), meetsContrastAA()

🔧 Enhanced

• Code Quality: Major refactoring of WCAG contrast calculations across all components
  • Extracted duplicate WCAG code (~150+ lines) into shared HuxWCAG utility class
  • Standardized all components to use proper WCAG 2.1 calculation (replaced computeLuminance() with manual WCAG formula)
  • Updated components: HuxButton, HuxDropdown, HuxPagination, HuxToggle, HuxCheckbox, HuxBadge
  • Improved maintainability with single source of truth for contrast calculations
  • Enhanced consistency and accuracy of accessibility calculations
  • No breaking changes - all changes are internal improvements
