feat: add GitHub Actions workflow for Docker image builds

- Created docker-build.yml workflow for automated Docker builds
- Configured GitHub Container Registry (ghcr.io) with GITHUB_TOKEN auth
- Added multi-architecture support (linux/amd64, linux/arm64)
- Integrated Trivy security scanning for vulnerability detection
- Implemented smart tagging based on branches, PRs, and releases
- Added build caching for improved performance
- Updated Dockerfiles with OCI labels for proper ghcr.io linking
- Created comprehensive README-DOCKER.md documentation

The workflow automatically builds and pushes images on:
- Push to main/develop branches
- Pull requests (build only, no push)
- Release publications
- Manual workflow dispatch

+# Docker Build and Push Workflow
+
+This GitHub Actions workflow automatically builds and pushes Docker images for both the backend and frontend to GitHub Container Registry (ghcr.io).
+
+## Features
+
+- 🔧 **Automatic builds** on push to main/develop branches, PRs, and releases
+- 🏗️ **Multi-architecture support** (linux/amd64 and linux/arm64)
+- 🏷️ **Smart tagging** based on branches, versions, and commits
+- 🔒 **Security scanning** with Trivy vulnerability scanner
+- 💾 **Build caching** for faster subsequent builds
+- 📊 **Build summaries** in GitHub Actions UI
+
+## Authentication
+
+The workflow uses the built-in `GITHUB_TOKEN` for authentication with GitHub Container Registry. No additional setup or personal access tokens are required.
+
+### Required Permissions
+
+The workflow automatically sets the necessary permissions:
+- `contents: read` - To checkout the repository
+- `packages: write` - To push images to ghcr.io
+- `security-events: write` - To upload security scan results
+
+## Image Tags
+
+Images are automatically tagged based on the trigger event:
+
+| Event | Tags Generated |
+|-------|---------------|
+| Push to main | `latest`, `main`, `main-<short-sha>` |
+| Push to develop | `develop`, `develop-<short-sha>` |
+| Pull Request | `pr-<number>` |
+| Release (v1.2.3) | `1.2.3`, `1.2`, `1`, `latest` |
+| Manual trigger | Based on branch + optional push |
+
+## Usage
+
+### Pull Images
+
+Once published, images can be pulled using:
+
+```bash
+# Pull backend image
+docker pull ghcr.io/the-luap/picpeak/backend:latest
+
+# Pull frontend image
+docker pull ghcr.io/the-luap/picpeak/frontend:latest
+
+# Pull specific version
+docker pull ghcr.io/the-luap/picpeak/backend:v1.0.0
+
+# Pull for specific architecture
+docker pull --platform linux/arm64 ghcr.io/the-luap/picpeak/backend:latest
+```
+
+### Using in Docker Compose
+
+```yaml
+version: '3.8'
+
+services:
+  backend:
+    image: ghcr.io/the-luap/picpeak/backend:latest
+    environment:
+      - NODE_ENV=production
+    ports:
+      - "3001:3000"
+
+  frontend:
+    image: ghcr.io/the-luap/picpeak/frontend:latest
+    ports:
+      - "80:80"
+```
+
+### Using in Kubernetes
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: picpeak-backend
+spec:
+  replicas: 3
+  template:
+    spec:
+      containers:
+      - name: backend
+        image: ghcr.io/the-luap/picpeak/backend:latest
+        imagePullPolicy: Always
+```
+
+## Manual Workflow Trigger
+
+You can manually trigger the workflow from the Actions tab:
+
+1. Go to Actions → "Build and Push Docker Images"
+2. Click "Run workflow"
+3. Select branch and whether to push images
+4. Click "Run workflow"
+
+## Security Scanning
+
+The workflow includes Trivy vulnerability scanning that:
+- Scans for CRITICAL and HIGH severity vulnerabilities
+- Uploads results to GitHub Security tab
+- Available under Security → Code scanning alerts
+
+## Build Optimization
+
+The workflow uses several optimization techniques:
+
+1. **GitHub Actions Cache**: Speeds up builds by caching layers
+2. **Multi-stage builds**: Reduces final image size
+3. **Parallel builds**: Backend and frontend build simultaneously
+4. **Smart rebuilds**: Only rebuilds changed components
+
+## Troubleshooting
+
+### Permission Denied Errors
+
+If you encounter permission errors when pushing images:
+
+1. **First-time setup**: The first push creates a private package. You may need to:
+   - Go to your package settings at `https://github.com/users/YOUR_USERNAME/packages`
+   - Link the package to your repository
+   - Set package visibility (public/private)
+
+2. **Organization repositories**: Ensure the organization allows GitHub Actions to create packages
+
+### Build Failures
+
+Check the workflow logs in the Actions tab for detailed error messages. Common issues:
+- Missing dependencies in package.json
+- Dockerfile syntax errors
+- Network issues during package installation
+
+### Image Not Found
+
+If images aren't visible after successful push:
+- Check package visibility settings
+- Ensure you're authenticated to pull private images:
+  ```bash
+  echo $GITHUB_TOKEN | docker login ghcr.io -u YOUR_USERNAME --password-stdin
+  ```
+
+## Package Management
+
+### View Packages
+
+Your Docker images are available at:
+- Backend: `https://github.com/users/the-luap/packages/container/package/picpeak%2Fbackend`
+- Frontend: `https://github.com/users/the-luap/packages/container/package/picpeak%2Ffrontend`
+
+### Delete Old Versions
+
+To save storage, you can delete old versions:
+1. Go to package settings
+2. Click on "Manage versions"
+3. Select versions to delete
+4. Click "Delete selected versions"
+
+### Set Retention Policy
+
+Configure automatic cleanup in package settings:
+1. Go to package settings
+2. Click on "Manage Actions access"
+3. Set retention days for untagged versions
+
+## Best Practices
+
+1. **Use semantic versioning** for releases (e.g., v1.2.3)
+2. **Test images locally** before pushing to production
+3. **Monitor security alerts** from Trivy scans
+4. **Clean up old images** regularly to save storage
+5. **Use specific tags** in production (avoid `latest`)
+
+## Advanced Configuration
+
+### Custom Registry
+
+To use a different registry, update the workflow:
+
+```yaml
+env:
+  REGISTRY: docker.io  # or your custom registry
+  BACKEND_IMAGE_NAME: yourusername/picpeak-backend
+```
+
+### Additional Platforms
+
+To build for more platforms:
+
+```yaml
+platforms: linux/amd64,linux/arm64,linux/arm/v7
+```
+
+### Custom Build Arguments
+
+Add build arguments in the workflow:
+
+```yaml
+build-args: |
+  NODE_VERSION=20
+  API_URL=${{ secrets.API_URL }}
+```
