Add approximate nearest neighbor infrastructure to vec0: shared distance dispatch (vec0_distance_full), flat index type with parser, NEON-optimized cosine/Hamming for float32/int8, amalgamation script, and benchmark suite (benchmarks-ann/) with ground-truth generation and profiling tools. Remove unused vec_npy_each/vec_static_blobs code, fix missing stdint.h include.
