What’s New

🔧 Code Organization & Standards

JSX File Extension Refactoring

This release implements a comprehensive refactoring to improve code clarity and resolve Vite OXC parser issues:

Renamed JSX Files: All React component files containing JSX syntax are now explicitly marked with .jsx extension
Import Updates: Updated all imports across the application to reflect new file extensions
Vite Configuration: Updated build configuration to properly handle .jsx files
Improved Clarity: Pure JavaScript files (like i18n.js and store.js) retain .js extension for clear distinction

This change follows React best practices and improves developer experience by making it immediately clear which files contain JSX syntax.

🐛 Critical Bug Fixes

Memory Leak Fixes

MainChart Memory Leak: Fixed memory leak in MainChart component by adding proper cleanup function for ColorSchemeChange event listener
Improved Stability: Enhanced component lifecycle management prevents memory accumulation in long-running applications

Functionality Improvements

Random Function Fix: Corrected random number generator to properly accept min/max parameters
Better Performance: These fixes ensure stable memory usage in production environments
