feat(docker): add Docker support for containerized deployment

- Add multi-stage Dockerfile with Node.js 20 Alpine
- Add docker-compose.yml for easy deployment
- Add .dockerignore to optimize build context
- Enable standalone output in next.config.ts
- Add Docker deployment documentation to README
- Move Docker support from planned to completed in roadmap

The Dockerfile uses a three-stage build process:
1. deps: Install production dependencies
2. builder: Build Next.js application
3. runner: Minimal production runtime with non-root user

Includes health checks, restart policy, and security best practices.

+### Quick Start with Docker
+
+```bash
+# Build the Docker image
+docker build -t tuxmate:latest .
+
+# Run the container
+docker run -p 3000:3000 tuxmate:latest
+```
+
+### Using Docker Compose (Recommended)
+
+```bash
+# Start the application
+docker-compose up -d
+
+# View logs
+docker-compose logs -f
+
+# Stop the application
+docker-compose down
+```
+
+Open [http://localhost:3000](http://localhost:3000)
+
+### Configuration
+
+The Docker container exposes port 3000 by default. You can customize the port mapping:
+
+```bash
+docker run -p 8080:3000 tuxmate:latest
+```
