This implementation includes:

1. A complete Next.js application with Persian (Farsi) as default language
2. Three main tabs: Chat Interface, Code Editor, and Agent Workflow
3. Voice control integration points
4. Code generation and execution capabilities
5. Task management for the AI agent
6. Responsive design with Tailwind CSS
7. RTL support for Persian language
8. Docker configuration for deployment
9. API routes for chat and code generation
10. Modular component structure

To run this application:

1. Install dependencies: `npm install`
2. Run development server: `npm run dev`
3. Build for production: `npm run build`
4. Start production server: `npm start`

For Docker deployment:
1. Build the image: `docker build -t ghadirsync-ai .`
2. Run the container: `docker run -p 3000:3000 ghadirsync-ai`

The application will be available at http://localhost:3000

Key features implemented:
- Persian-first UI with language toggle
- Voice command integration
- AI agent workflow visualization
- Code editor with syntax highlighting
- Project scaffolding
- Responsive design
- Docker support
- Offline-first approach

Additional features can be added by extending the existing components and API routes.
