WIP: ES6 module conversion and webpack refactoring

- Convert all IIFE modules to ES6 modules with attach functions
- Split webpack configs: lib build vs demo build
- Add UMD wrapper for auto-initialization with jQuery
- Update package.json with sequential build scripts
- Clean up legacy dist files and reorganize demo structure

Status: jQuery timing issues remain - attach functions not accessible
Next: Debug UMD factory execution and jQuery parameter passing
