Module vector 

Vector search implementation using approximate nearest neighbor algorithms.

This module provides vector (semantic) search functionality through various index structures (Flat, HNSW, IVF), supporting cosine similarity, Euclidean distance, and other distance metrics.

Module Structure

• core: Core data structures (vector, distance, quantization)
• index: Index management (config, factory, traits, flat, hnsw, ivf)
• search: Search execution (similarity, ranking, result processing)
• store: High-level store interface
• writer: Index writer trait
