Convert to full-stack Railway deployment

- Create unified Dockerfile that builds both frontend and backend
- Update backend to serve static frontend files
- Configure frontend to connect to same domain WebSocket
- Update Railway configuration for single-service deployment
- Add comprehensive deployment documentation
- Optimize with .dockerignore for faster builds

This eliminates the need for separate Netlify + Railway deployment.
Now everything runs on Railway as a single service.

+# Full-Stack Railway Deployment
+
+Deploy the entire DevOps Learn platform to Railway as a single service.
+
+## Architecture
+
+- **Single Railway Service**: Backend serves both WebSocket API and static frontend
+- **Frontend**: Next.js static export served by Express
+- **Backend**: Node.js WebSocket server with Docker scenario support
+- **Scenarios**: Kubernetes containers with kind clusters
+
+## Deployment Steps
+
+### 1. Deploy to Railway
+
+1. **Create Railway Account**: Go to [railway.app](https://railway.app)
+2. **New Project** → **Deploy from GitHub repo**
+3. **Select this repository** (root directory)
+4. **Set Environment Variables**:
+   ```
+   NODE_ENV=production
+   PORT=3000
+   ```
+5. **Deploy**: Railway will use the root Dockerfile automatically
+
+### 2. How It Works
+
+1. **Build Process**:
+   - Frontend builds to static files (`out/`)
+   - Backend TypeScript compiles to JavaScript
+   - Docker scenario images are built
+   - Everything is packaged in a single container
+
+2. **Runtime**:
+   - Express server serves static frontend files
+   - Same server handles WebSocket connections for scenarios
+   - Frontend connects to backend on same domain (no CORS issues)
+
+### 3. Benefits
+
+✅ **Simplified Deployment**: One service, one URL  
+✅ **No CORS Issues**: Frontend and backend on same domain  
+✅ **Cost Effective**: Single Railway service ($5/month free credit)  
+✅ **Docker Support**: Full scenario functionality  
+✅ **WebSocket Support**: Real-time terminal connections  
+
+### 4. Local Development
+
+```bash
+# Frontend development
+npm run dev
+
+# Backend development  
+cd src/server
+npm run dev
+
+# Full stack test
+npm run build
+npm run railway:start
+```
+
+### 5. Environment Variables
+
+**Required**:
+- `PORT` - Server port (set by Railway automatically)
+
+**Optional**:
+- `NODE_ENV=production` 
+- `FRONTEND_URL` - For CORS (not needed in full-stack mode)
+
+## File Structure

+- **Railway**: $5/month free credit
+- **Total**: $0/month for starter projects
+
+Perfect for learning and prototyping! 🚀
