//! # Security Analyzer
//! 
//! Comprehensive security analysis module that performs multi-layered security assessment:
//! - Configuration security analysis (secrets, insecure settings)
//! - Code security patterns (language/framework-specific issues)
//! - Infrastructure security (Docker, compose configurations)
//! - Security policy recommendations and compliance guidance
//! - Security scoring with actionable remediation steps
