//! SIMD-accelerated rolling window operations
//!
//! This module provides high-performance rolling window calculations using:
//! - Portable SIMD via the `wide` crate (works on stable Rust)
//! - Algorithmic optimizations (deque-based min/max, Welford's algorithm for std)
//! - Smart thresholds to avoid SIMD overhead on small arrays
