//! Probabilistic Data Structures for Streaming Analytics
//!
//! This module provides memory-efficient streaming algorithms for:
//! - DDSketch: O(1) percentile queries (P50, P90, P95, P99)
//! - HyperLogLog: Cardinality estimation (unique counts)
//! - ExponentialHistogram: Mergeable histograms for rollups
//! - CountMinSketch: Frequency estimation for top-K queries
//! - AdaptiveSketch: Memory-efficient latency tracking (sparse → dense)
