feat(agents): implement Maria Quitéria security auditor agent

- Add MariaQuiteriaAgent class with security auditing capabilities
- Implement threat detection and vulnerability assessment
- Add compliance verification (LGPD, ISO27001, OWASP, GDPR)
- Create intrusion detection and digital forensics features
- Add risk assessment and security monitoring
- Implement process method for agent request handling
- Add API route at /api/v1/agents/maria-quiteria
- Register agent in lazy loader with proper configuration
- Create comprehensive unit tests for security functionality
