//! Sparse vector support for efficient storage and search of high-dimensional sparse embeddings.
//!
//! This module provides:
//! - Sparse vector type with COO (Coordinate) format storage
//! - Efficient sparse-sparse distance computations
//! - PostgreSQL operators and functions
//! - Support for BM25, SPLADE, and learned sparse representations
