Preact Demo Successfully Updated! ✅

I've modernized the preact demo to the latest versions and build tools as requested.

Todo List:

• Analyze current preact demo setup
• Update package.json with latest versions
• Update imports and syntax for Preact X (10.x)
• Update build tools and ESLint config
• Fix any breaking changes from Preact 8→10 migration
• Test build process
• Commit changes

Major Updates Made:

📦 Package Updates:

• Preact: 8.2.6 → 10.26.9 (major version upgrade)
• Preact CLI: 2.1.0 → 3.5.1
• ESLint: 4.9.0 → 9.16.0 (with modern configuration)
• Jest: 21.2.1 → 29.7.0 (with jsdom environment)

🔧 Build Modernization:

• Replaced outdated Babel configuration with modern setup
• Added proper JSX transformation with @babel/plugin-transform-react-jsx
• Updated ESLint config to use current standards
• Removed preact-compat dependency (not needed with Preact X)

⚛️ Code Modernization:

• Converted App component from class to function component with hooks
• Converted PrivateRoute from class to function component
• Added proper h import to test files
• All components now use modern Preact X patterns

The demo should now work with the latest Preact ecosystem and modern build tools. The outdated Babel setup has been completely replaced with a modern configuration.
