[1.0.0] - 2025-01-08 🎉

🚀 Major Performance Improvements

🏗️ Code Architecture Refactoring

• MAJOR: Restructured codebase from monolithic class to modular architecture
• NEW: Split functionality into three focused modules:
  • TextStat::BasicStats - Basic text statistics (char count, word count, syllable count, etc.)
  • TextStat::DictionaryManager - Dictionary loading, caching, and difficult words detection
  • TextStat::ReadabilityFormulas - All readability formulas and text standard calculation
• NEW: Added TextStat::Main class that delegates to appropriate modules
• COMPATIBILITY: Maintained 100% backward compatibility through method_missing delegation
• IMPROVEMENT: Better separation of concerns and improved code maintainability
