//! Clustering evaluation metrics
//!
//! This module provides comprehensive metrics for evaluating clustering algorithm performance.
//! Metrics are organized into focused submodules for better maintainability.
//!
//! # Basic Metrics
//! - Silhouette coefficient for measuring cluster cohesion and separation
//! - Davies-Bouldin index for evaluating cluster separation
//! - Calinski-Harabasz index for measuring between-cluster vs within-cluster variance
//! - Adjusted Rand Index and Normalized Mutual Information for comparing clusterings
//!
//! # Advanced Metrics
//! - Dunn index for cluster separation quality
//! - BIC/AIC scores for model selection
//!
//! # Information-Theoretic Metrics
//! - Jensen-Shannon divergence between clusterings
//! - Variation of Information
//! - Information-theoretic cluster quality measures
//!
//! # Stability Analysis
//! - Bootstrap confidence intervals
//! - Multi-scale stability analysis
//! - Noise perturbation analysis
