//! Fast HNSW primitives for MemWAL's in-memory vector index.
//!
//! The graph takes the hnswlib layout as the performance baseline while
//! keeping MemWAL-specific constraints explicit: vector data is borrowed from
//! Arrow batches, graph publication follows a multi-reader / single-writer
//! lifecycle, and flush snapshots emit Lance's HNSW sub-index batch format.
