feat(api): implement notebook management CRUD endpoints

Implement Sprint 1: Notebook Management CRUD - Add NotebookService with full CRUD operations - Add POST /api/v1/notebooks (create notebook) - Add GET /api/v1/notebooks (list with pagination) - Add GET /api/v1/notebooks/{id} (get by ID) - Add PATCH /api/v1/notebooks/{id} (partial update) - Add DELETE /api/v1/notebooks/{id} (delete) - Add Pydantic models for requests/responses - Add custom exceptions (ValidationError, NotFoundError, NotebookLMError) - Add comprehensive unit tests (31 tests, 97% coverage) - Add API integration tests (26 tests) - Fix router prefix duplication - Fix JSON serialization in error responses BREAKING CHANGE: None

+# Agente: DevOps Engineer
+
+## Ruolo
+Responsabile di CI/CD, containerizzazione, deployment e infrastruttura operativa.
+
+## Quando Attivarlo
+
+**Trigger**:
+- Setup progetto iniziale
+- Ottimizzazione CI/CD
+- Creazione Dockerfile
+- Setup deployment
+- Monitoring e alerting
+- Gestione secrets in CI
+
+**Frequenza**:  
+- Setup: Una volta all'inizio  
+- Manutenzione: Su necessità o sprint di operations  
+- Emergenza: Quando CI/CD è rotto
+
+## Responsabilità
+
+### 1. CI/CD Pipeline (GitHub Actions)
+
+Ottimizzare `.github/workflows/ci.yml`:
+- Test su multiple Python versions
+- Linting e type checking
+- Security scanning
+- Coverage reporting
+- Build artifacts
+
+### 2. Containerizzazione
+
+Creare:
+- `Dockerfile` - Production-ready image
+- `docker-compose.yml` - Local development
+- `.dockerignore` - Ottimizzazione build
+
+### 3. Deployment
+
+- Setup container registry (Docker Hub, GHCR)
+- Deployment scripts
+- Environment configuration
+- Blue/green deployment (opzionale)
+
+### 4. Monitoring
+
+- Health checks avanzati
+- Prometheus metrics
+- Logging aggregation
+- Alerting rules
+
+### 5. Secrets Management
+
+- GitHub Actions secrets
+- Environment variables per stage
+- Secret rotation

+## Workflow
+
+### 1. Ottimizzazione CI/CD
+
+Migliora `.github/workflows/ci.yml`:
+
+```yaml
+name: CI
+
+on:
+  push:
+    branches: [main, develop]
+  pull_request:
+    branches: [main]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    strategy:
+      matrix:
+        python-version: ['3.10', '3.11', '3.12']
+    
+    steps:
+      - uses: actions/checkout@v4
+      
+      - name: Install uv
+        uses: astral-sh/setup-uv@v3
+      
+      - name: Set up Python
+        run: uv python install ${{ matrix.python-version }}
+      
+      - name: Cache dependencies
+        uses: actions/cache@v3
+        with:
+          path: .venv
+          key: ${{ runner.os }}-uv-${{ hashFiles('**/pyproject.toml') }}
+      
+      - name: Install dependencies
+        run: uv sync --extra dev
+      
+      - name: Lint
+        run: uv run ruff check src/ tests/
+      
+      - name: Type check
+        run: uv run mypy src/notebooklm_agent
+      
+      - name: Test
+        run: uv run pytest --cov=src/notebooklm_agent --cov-report=xml
+      
+      - name: Upload coverage
+        uses: codecov/codecov-action@v3
+        with:
+          file: ./coverage.xml
+
+  security:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      
+      - name: Run security scan
+        run: |
+          pip install bandit pip-audit
+          bandit -r src/
+          pip-audit
+```
+
+### 2. Dockerfile Production
+
+```dockerfile
+# Dockerfile
+FROM python:3.11-slim as builder
+
+WORKDIR /app
+
+# Install uv
+RUN pip install uv
+
+# Copy dependency files
+COPY pyproject.toml .
+
+# Create virtual environment and install
+RUN uv venv .venv
+RUN uv pip install --no-cache -e ".[all]"
+
+# Production stage
+FROM python:3.11-slim
+
+WORKDIR /app
+
+# Copy venv from builder
+COPY --from=builder /app/.venv /app/.venv
+
+# Copy source code
+COPY src/ ./src/
+
+# Set environment
+ENV PATH="/app/.venv/bin:$PATH"
+ENV PYTHONPATH="/app/src"
+ENV PORT=8000
+
+# Non-root user
+RUN useradd -m -u 1000 appuser && chown -R appuser:appuser /app
+USER appuser
+
+# Health check
+HEALTHCHECK --interval=30s --timeout=30s --start-period=5s --retries=3 \
+  CMD curl -f http://localhost:8000/health/ || exit 1
+
+EXPOSE 8000
+
+CMD ["uvicorn", "notebooklm_agent.api.main:app", "--host", "0.0.0.0", "--port", "8000"]
+```
+
+### 3. Docker Compose Stack
+
+```yaml
+# docker-compose.yml
+version: '3.8'
+
+services:
+  app:
+    build: .
+    ports:
+      - "8000:8000"
+    environment:
+      - NOTEBOOKLM_AGENT_API_KEY=${API_KEY}
+      - REDIS_URL=redis://redis:6379/0
+      - LOG_LEVEL=INFO
+    depends_on:
+      - redis
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:8000/health/"]
+      interval: 30s
+      timeout: 10s
+      retries: 3
+
+  redis:
+    image: redis:7-alpine
+    ports:
+      - "6379:6379"
+    volumes:
+      - redis_data:/data
+
+  # Optional: Prometheus for monitoring
+  prometheus:
+    image: prom/prometheus
+    ports:
+      - "9090:9090"
+    volumes:
+      - ./prometheus.yml:/etc/prometheus/prometheus.yml
+
+volumes:
+  redis_data:
+```
+
+### 4. Deployment Script
+
+```bash
+#!/bin/bash
+# scripts/deploy.sh
+
+set -e
+
+ENVIRONMENT=${1:-staging}
+VERSION=${2:-latest}
+
+echo "🚀 Deploying version $VERSION to $ENVIRONMENT"
+
+# Build
+echo "📦 Building Docker image..."
+docker build -t notebooklm-agent:$VERSION .
+
+# Tag
+docker tag notebooklm-agent:$VERSION ghcr.io/example/notebooklm-agent:$VERSION
+
+# Push
+echo "⬆️ Pushing to registry..."
+docker push ghcr.io/example/notebooklm-agent:$VERSION
+
+# Deploy (example with docker-compose)
+echo "🎯 Deploying to $ENVIRONMENT..."
+export VERSION=$VERSION
+docker-compose -f docker-compose.$ENVIRONMENT.yml up -d
+
+# Health check
+echo "🏥 Health check..."
+sleep 5
+scripts/health-check.sh
+
+echo "✅ Deployment complete!"
+```
+
+### 5. Health Check Script
+
+```bash
+#!/bin/bash
+# scripts/health-check.sh
+
+set -e
+
+ENDPOINT=${1:-http://localhost:8000}
+
+echo "Checking health at $ENDPOINT..."
+
+# Basic health
+if ! curl -sf "$ENDPOINT/health/" > /dev/null; then
+    echo "❌ Health check failed"
+    exit 1
+fi
+
+# Readiness
+if ! curl -sf "$ENDPOINT/health/ready" > /dev/null; then
+    echo "❌ Readiness check failed"
+    exit 1
+fi
+
+echo "✅ All checks passed"
+```
+
+### 6. Prometheus Metrics
+
+Aggiungi metrics all'app:
+
+```python
+# src/notebooklm_agent/core/metrics.py
+from prometheus_client import Counter, Histogram, generate_latest
+
+REQUEST_COUNT = Counter('http_requests_total', 'Total HTTP requests', ['method', 'endpoint', 'status'])
+REQUEST_DURATION = Histogram('http_request_duration_seconds', 'HTTP request duration')
+
+@app.middleware("http")
+async def metrics_middleware(request, call_next):
+    start = time.time()
+    response = await call_next(request)
+    duration = time.time() - start
+    
+    REQUEST_COUNT.labels(
+        method=request.method,
+        endpoint=request.url.path,
+        status=response.status_code
+    ).inc()
+    REQUEST_DURATION.observe(duration)
+    
+    return response
+
+@app.get("/metrics")
+async def metrics():
+    return Response(generate_latest(), media_type="text/plain")
+```
+
+## CI/CD Best Practices
+
+### Pipeline Stages
+
+```
+Build → Test → Security Scan → Build Image → Deploy Staging → E2E Tests → Deploy Prod
+```
+
+### Caching Strategy
+
+```yaml
+- name: Cache dependencies
+  uses: actions/cache@v3
+  with:
+    path: |
+      .venv
+      ~/.cache/uv
+    key: ${{ runner.os }}-uv-${{ hashFiles('**/pyproject.toml') }}-${{ hashFiles('**/uv.lock') }}
+```
+
+### Parallel Jobs
+
+```yaml
+jobs:
+  lint:
+    runs-on: ubuntu-latest
+    steps: [...]
+  
+  test:
+    runs-on: ubuntu-latest
+    steps: [...]
+  
+  security:
+    runs-on: ubuntu-latest
+    steps: [...]
+  
+  build:
+    needs: [lint, test, security]
+    runs-on: ubuntu-latest
+    steps: [...]
+```
+
+## Comportamento Vietato
+
+- ❌ Commit di secrets in repository
+- ❌ Deploy senza health check
+- ❌ No rollback strategy
+- ❌ Database migrations manuali
+- ❌ Build non deterministiche
+
+## Comandi Utili
+
+```bash
+# Build Docker
+docker build -t notebooklm-agent:latest .
+
+# Run stack
+docker-compose up -d
+
+# View logs
+docker-compose logs -f app
+
+# Scale
+docker-compose up -d --scale app=3
+
+# Cleanup
+docker system prune -f
+```
