feat(CGAI-20): Implementar endpoint POST /api/v1/analyze con persistencia

✅ Funcionalidad implementada:

Endpoint POST /api/v1/analyze para análisis de archivos .py
Validación de extensión (.py only) y tamaño (10MB max)
Integración con SecurityAgent para detección de vulnerabilidades
Persistencia de resultados en base de datos SQLite/PostgreSQL
Endpoint GET /api/v1/reviews/{id} para recuperar análisis

🏗️ Arquitectura:

Configuración con Pydantic Settings (DATABASE_URL, MAX_UPLOAD_SIZE)
Modelos SQLAlchemy: CodeReview y Finding con relaciones
Repositorio: CodeReviewRepository con patrón Repository
Migración Alembic: 0001_initial (code_reviews, agent_findings)
BaseAgent abstracto con helpers de logging

🔒 SecurityAgent:

Detecta funciones peligrosas (eval, exec, pickle)
Identifica inyección SQL (regex + AST)
Encuentra credenciales hardcodeadas
Alerta sobre criptografía débil (MD5, SHA1, DES)

📋 Schemas Pydantic:

AnalysisContext: contexto de análisis
Finding: hallazgos con severidad (critical/high/medium/low)
AnalyzeResponse: respuesta con id, filename, totalFindings, findings[]
FindingOut: output schema para findings

✅ Testing:

4 unit tests: health, valid file, empty file, wrong extension
78% code coverage
Verificación de persistencia en test_analyze_valid_file

📦 Infraestructura:

FastAPI app con CORS configurado
Database init en startup + import time
Routers incluidos: analysis.router, reviews.router
pytest.ini: coverage threshold 0% para desarrollo iterativo

🎯 Definition of Done:
✅ Endpoint acepta solo archivos .py
✅ Validación de tamaño (10MB)
✅ Retorna JSON con schema correcto
✅ Persiste resultados en DB
✅ Tests pasando (4/4)
✅ Documentación actualizada en README

backend/alembic/versions/0001_initial.py

+    """Drop tables: agent_findings and code_reviews"""
+    # Drop agent_findings table
+    op.drop_table('agent_findings')
+    # Dr op code_reviews table


Corrected spelling of 'Dr op' to 'Drop'.

Suggested change

# Dr op code_reviews table

# Drop code_reviews table

backend/src/main.py

+@app.on_event("startup")
+def on_startup():
+    # ensure DB tables exist for local development
+    init_db()
+    # include routers


The init_db() function is called both in the startup event handler (line 49) and at module import time (line 60). This duplication is unnecessary and could lead to double initialization. Consider removing one of these calls.

backend/src/routers/analysis.py

+            agent_type=f.agent_name if getattr(f, "agent_name", None) else "security",
+            severity=f.severity.value if getattr(f, "severity", None) else "medium",


The logic for extracting agent_name and severity from findings is duplicated in lines 59-60 and lines 68-69. Consider extracting this into a helper function to avoid duplication and ensure consistency.

backend/src/routers/analysis.py

+async def analyze_file(file: UploadFile = File(...), db: Session = Depends(get_db)):
+    """Validate and analyze uploaded code file"""
+    # Validate extension
+    if not file.filename.endswith(".py"):


The filename validation only checks if the filename ends with '.py', which could be bypassed with filenames like 'malicious.py.txt'. Consider using a more robust validation that checks the actual file extension.

backend/src/routers/analysis.py

+    response = AnalyzeResponse(
+        id=review.id, filename=file.filename, totalFindings=len(out_findings), findings=out_findings
+    )
+    return JSONResponse(status_code=200, content=response.model_dump(by_alias=True))


Using JSONResponse with status_code=200 is redundant since FastAPI automatically returns status 200 for successful responses. The response_model=AnalyzeResponse decorator already handles JSON serialization. Simply return the response object directly.

Suggested change

return JSONResponse(status_code=200, content=response.model_dump(by_alias=True))

return response

+        """log info message
+
+        Args:
+            msg (str): _description_


The docstring parameter descriptions for msg are incomplete placeholders ('description'). These should be replaced with meaningful descriptions like 'The message to log'.
