🚀 FINAL FIX: Standard dynamic imports with proper async handling

- Replace Function() constructor imports with standard dynamic imports
- Add proper state management for template engine loading (null | false | Liquid)
- Fix async initialization timing issues with lazy loading
- Add mustache type declarations for TypeScript compatibility
- Prevent retry attempts on failed module loads
- Ensure webpack/bundler compatibility across all environments

All webpack compatibility issues now fully resolved.
