//! Code metrics module - Layer 3
//!
//! This module provides code complexity metrics:
//! - Cyclomatic complexity (McCabe)
//! - Cognitive complexity (SonarSource)
//! - Lines of code
//! - Nesting depth
//!
//! # Session 15 Additions
//!
//! New metrics types and utilities:
//! - `types` - Shared metric data structures (LocInfo, CognitiveInfo, etc.)
//! - `file_utils` - File handling utilities (size checks, binary detection)
//!
//! Session 15 Phase 2 additions:
//! - `loc` - Lines of code analysis with language-aware comment detection
//!
//! Session 15 Phase 3 additions:
//! - `cognitive` - Cognitive complexity with SonarQube algorithm
//!
//! Session 15 Phase 5 additions:
//! - `halstead` - Standalone Halstead software science metrics per function
//!
//! # References
//! - McCabe, T.J. (1976). "A Complexity Measure"
//! - SonarSource Cognitive Complexity whitepaper
//! - Halstead, M.H. (1977). "Elements of Software Science"
