SIMDVec Supercharges Vector Hunt

Elasticsearch simdvec is the engine behind every vector distance computation in Elasticsearch. It provides hand-tuned AVX-512 and NEON kernels for every vector type Elasticsearch supports. In bulk scoring (where production actually lives), the hand-tuned SIMD kernel library powering all vector distance computations in Elasticsearch, processes float32 vectors at 95 ns/vector. FAISS is at 165 ns. jvector at 412 ns on x86. That's 4x. The gap widens with scale. Once you exceed CPU cache capacity, si
