Add a Basic Web Playground for Component Generation

#### Description
The project currently operates as a CLI tool, which limits its accessibility for users who prefer a graphical interface. Adding a basic web-based playground would allow users to interact with the generator through a browser, providing a more user-friendly experience. This playground could serve as a demo or testing environment for generating Preact components.

#### Proposed Solution
Develop a simple web interface where users can:
1. Input a description of the component they want to generate.
2. Submit the description to the backend API (to be implemented).
3. View the generated files directly in the browser or download them.

#### Suggested Implementation
1. **Frontend Framework**: Use a lightweight framework like React or plain HTML/CSS/JavaScript for simplicity.
2. **Backend Integration**: Connect the frontend to the API endpoints (e.g., `/generate`) for generating components.
3. **Features**:
- A text input field for the component description.
- A "Generate" button to submit the description.
- A results section to display the generated files (file names and content).
- A download option for the generated files.

#### Example Design
- **Input Section**: A text area for entering the component description.
- **Output Section**: A list of generated files with their content displayed in collapsible panels.
- **Actions**: A button to download all files as a ZIP.

#### Tasks
1. Create a new directory for the web playground (e.g., playground).
2. Develop the frontend interface.
3. Set up the backend API integration.
4. Add basic styling for a clean and intuitive user experience.
5. Write documentation for running the playground locally.

#### Additional Notes
- Ensure the playground is lightweight and easy to set up.
- Use a development server (e.g., Vite, Webpack Dev Server) for local testing.
- Consider adding CORS support to the backend API if needed.
- Optionally, deploy the playground to a platform like Vercel or Netlify for public access.

This enhancement will make the project more accessible and provide a visual way for users to test the generator.
