feat: serverless 2.0.0 architecture with Authentik auth proxy

Implements a complete serverless development container platform:

## Architecture
- Authentik forward auth for authentication/authorization
- NGINX routing proxy extracts GitHub repo from URL path
- Knative Service auto-scales dev container instances from 0
- Dynamic GitHub repo routing via /github/{owner}/{repo}

## Components
- routing-proxy: NGINX-based service for repo extraction and forwarding
- deployment.yaml: Complete K8s manifests (proxy, Knative, ingress, secrets)
- authentik-config.yaml: Authentik application and provider configs
- serverless scripts: Dynamic repo initialization and startup handling
- Comprehensive documentation and Makefile for ops

## Key Features
- Scale to zero when not in use (cost-effective)
- Per-request isolation (each repo gets own container)
- Built-in file manager for upload/download
- Support for private repos via GitHub tokens
- User attribution via Authentik headers
- WebSocket support for VNC connections

Example usage: https://devcontainer.farh.net/github/microsoft/vscode

+# DevContainer Serverless 2.0
+
+A serverless, auto-scaling development container platform with dynamic GitHub repository routing, secured by Authentik authentication.
+
+## Architecture Overview
+
+```
+User Request: https://devcontainer.farh.net/github/microsoft/vscode
+     ↓
+Authentik (Authentication & Authorization)
+     ↓ (authenticated request with user headers)
+NGINX Ingress (SSL termination, rate limiting)
+     ↓
+Routing Proxy (extracts GitHub repo from URL, adds headers)
+     ↓ (with X-GitHub-Repo header)
+Knative Service (devcontainer-serverless)
+     ↓ (auto-scales from 0 to N instances)
+Dev Container Instances (ephemeral, repo-specific)
+```
+
+### Key Features
+
+- 🚀 **Scale to Zero**: Containers automatically scale down to zero when not in use
+- 🔐 **Authentik Integration**: Full authentication and authorization via Authentik
+- 🐙 **Dynamic GitHub Routing**: Access any repo via `/github/{owner}/{repo}`
+- ⚡ **Fast Cold Start**: Optimized startup for quick repository access
+- 📁 **Built-in File Manager**: Upload/download files via web interface
+- 🛠️ **Multiple IDEs**: VSCode, Antigravity, or headless mode
+- 🎯 **Per-User Isolation**: Each request gets its own container instance
+
+## Quick Start
+
+### Prerequisites
+
+- Kubernetes cluster with Knative Serving installed
+- Authentik deployed and configured
+- NGINX Ingress Controller
+- cert-manager for SSL certificates
+
+### 1. Deploy the Serverless Components
+
+```bash
+# Create namespace and deploy all components
+kubectl apply -f serverless/deployment.yaml
+
+# Build and push the routing proxy image
+cd serverless/routing-proxy
+docker build -t ghcr.io/cpfarhood/devcontainer-routing-proxy:latest .
+docker push ghcr.io/cpfarhood/devcontainer-routing-proxy:latest
+```
+
+### 2. Configure Authentik
+
+```bash
+# Apply Authentik configuration
+kubectl apply -f serverless/authentik-config.yaml
+
+# Configure the application via Authentik web UI:
+# 1. Go to Applications > Providers > Create
+# 2. Type: Forward Auth (single application)
+# 3. Name: devcontainer-forward-auth-provider
+# 4. External host: https://devcontainer.farh.net
+# 5. Create the Application pointing to this provider
+```
+
+### 3. Update DNS and SSL
+
+```bash
+# Point devcontainer.farh.net to your ingress controller
+# The cert-manager will automatically provision SSL certificates
+```
+
+### 4. Test the Deployment
+
+```bash
+# Visit in browser (will redirect to Authentik for login)
+https://devcontainer.farh.net/github/microsoft/vscode
+
+# Check pod scaling
+kubectl get pods -n devcontainers -w
+
+# View logs
+kubectl logs -n devcontainers deployment/devcontainer-routing-proxy -f
+kubectl logs -n devcontainers -l serving.knative.dev/service=devcontainer-serverless -f
+```
+
+## Usage
+
+### URL Format
+
+```
+https://devcontainer.farh.net/github/{owner}/{repo}
+```
+
+### Examples
+
+```bash
+# Microsoft VSCode
+https://devcontainer.farh.net/github/microsoft/vscode
+
+# Kubernetes
+https://devcontainer.farh.net/github/kubernetes/kubernetes
+
+# Your private repo (requires GitHub token)
+https://devcontainer.farh.net/github/yourorg/private-repo
+```
+
+### Authentication Flow
+
+1. User visits `https://devcontainer.farh.net/github/owner/repo`
+2. NGINX Ingress checks with Authentik for authentication
+3. If not authenticated, redirects to Authentik login
+4. After successful login, request proceeds with user headers
+5. Routing proxy extracts repository from URL
+6. Knative spins up (or reuses) a container instance
+7. Container clones the specified repository and starts IDE
+
+### File Upload/Download
+
+Each container includes a built-in file manager accessible via the VNC web interface:
+
+1. Connect to your dev container via the browser
+2. Look for the file manager icon in the VNC toolbar
+3. Upload/download files directly through the web interface
+
+## Configuration
+
+### Environment Variables (Secret)
+
+Update the secret in `serverless/deployment.yaml`:
+
+```yaml
+stringData:
+  GITHUB_TOKEN: "ghp_your_github_token"      # For private repositories
+  VNC_PASSWORD: "your_secure_password"       # VNC access password
+  ANTHROPIC_API_KEY: "sk-ant-your_key"      # Claude API key
+  GIT_USER_NAME: "Your Name"                 # Git commit author
+  GIT_USER_EMAIL: "your.email@example.com"  # Git commit email
+```
+
+### Scaling Configuration
+
+Modify the Knative Service annotations in `deployment.yaml`:
+
+```yaml
+annotations:
+  autoscaling.knative.dev/minScale: "0"      # Scale to zero
+  autoscaling.knative.dev/maxScale: "20"     # Max instances
+  autoscaling.knative.dev/target: "1"        # 1 request per pod
+  autoscaling.knative.dev/scale-to-zero-grace-period: "10m"
+```
+
+### Resource Limits
+
+Adjust per-instance resources:
+
+```yaml
+resources:
+  requests:
+    memory: "1Gi"
+    cpu: "500m"
+  limits:
+    memory: "8Gi"    # More memory for large repos
+    cpu: "4000m"     # More CPU for compilation tasks
+```
+
+### IDE Selection
+
+Set the default IDE via environment variable:
+
+```yaml
+env:
+- name: IDE
+  value: "vscode"  # Options: vscode, antigravity, none
+```
+
+## Monitoring and Observability
+
+### Health Checks
+
+```bash
+# Routing proxy health
+curl http://devcontainer-routing-proxy.devcontainers.svc.cluster.local/health
+
+# Knative service status
+kn service describe devcontainer-serverless -n devcontainers
+
+# Check container logs
+kubectl logs -n devcontainers -l serving.knative.dev/service=devcontainer-serverless -f
+```
+
+### Metrics
+
+The setup includes Prometheus integration:
+
+- **Authentik metrics**: User authentication events
+- **Knative metrics**: Container scaling, cold starts, request latency
+- **NGINX metrics**: Request rates, response times
+- **Container metrics**: Resource usage per repository
+
+### Grafana Dashboards
+
+Import the provided dashboard for monitoring:
+
+```bash
+# TODO: Create Grafana dashboard JSON
+```
+
+## Security Considerations
+
+### Network Policies
+
+```yaml
+# Restrict networking between components
+apiVersion: networking.k8s.io/v1
+kind: NetworkPolicy
+metadata:
+  name: devcontainer-serverless-network-policy
+  namespace: devcontainers
+spec:
+  podSelector:
+    matchLabels:
+      serving.knative.dev/service: devcontainer-serverless
+  policyTypes:
+  - Ingress
+  - Egress
+  ingress:
+  - from:
+    - podSelector:
+        matchLabels:
+          app.kubernetes.io/component: routing-proxy
+    ports:
+    - protocol: TCP
+      port: 5800
+  egress:
+  - to: []  # Allow all outbound (needed for git clone, package installs)
+    ports:
+    - protocol: TCP
+      port: 443
+    - protocol: TCP
+      port: 80
+```
+
+### Repository Access Control
+
+Configure Authentik policies to control repository access:
+
+```python
+# Example Authentik expression policy
+github_repo = request.http_request.headers.get('X-GitHub-Repo', '')
+user_groups = [g.name for g in request.user.ak_groups.all()]
+
+# Allow admins access to everything
+if 'admins' in user_groups:
+    return True
+
+# Allow developers access to public repos and specific private repos
+if 'developers' in user_groups:
+    # Add logic for private repository access based on user attributes
+    if 'private-repo-access' in user.ak_attributes:
+        allowed_repos = user.ak_attributes['private-repo-access']
+        return github_repo in allowed_repos
+    return True  # Public repos only
+
+return False
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Container won't start**
+   ```bash
+   # Check Knative service status
+   kn service describe devcontainer-serverless -n devcontainers
+
+   # Check pod events
+   kubectl describe pod -n devcontainers -l serving.knative.dev/service=devcontainer-serverless
+   ```
+
+2. **Repository clone fails**
+   ```bash
+   # Check GitHub token in secret
+   kubectl get secret devcontainer-serverless-secrets -n devcontainers -o yaml
+
+   # Check container logs for git errors
+   kubectl logs -n devcontainers -l serving.knative.dev/service=devcontainer-serverless --tail=100
+   ```
+
+3. **Authentik authentication loop**
+   ```bash
+   # Check Authentik outpost logs
+   kubectl logs -n authentik -l app.kubernetes.io/name=authentik
+
+   # Verify ingress annotations
+   kubectl describe ingress devcontainer-serverless-ingress -n devcontainers
+   ```
+
+4. **Slow cold starts**
+   ```bash
+   # Check container startup time
+   kubectl logs -n devcontainers -l serving.knative.dev/service=devcontainer-serverless --timestamps
+
+   # Consider increasing timeout
+   # serving.knative.dev/timeoutSeconds: "900"  # 15 minutes
+   ```
+
+### Performance Tuning
+
+1. **Reduce cold start time**:
+   - Use minimal base image layers
+   - Pre-install common development tools
+   - Optimize git clone (shallow clone for large repos)
+
+2. **Resource optimization**:
+   - Set appropriate resource requests/limits
+   - Use `autoscaling.knative.dev/target-utilization-percentage`
+   - Consider persistent volumes for frequently accessed repos
+
+3. **Network optimization**:
+   - Use private container registry for faster image pulls
+   - Configure image pull policies appropriately
+   - Consider using a git cache proxy
+
+## Development
+
