…scalar tail (elastic#145316)

This PR fixes a small issue in bulk scoring functions where the last batch of vectors was unnecessarily dropped to the single-vector tail loop.

Bulk loops used c + 2 * batches - 1 < count as the loop condition, which exits when there aren't enough vectors for both the current batch AND a next batch to prefetch. This means the last full batch (where there's no next batch to prefetch) was always processed one-by-one in the scalar tail.

This PR changes the loop condition to c + batches - 1 < count (process all full batches), and guard the prefetch with const bool has_next = c + 2 * batches - 1 < count. This pattern was already used in vec_i4_2.cpp (AVX-512 int4) — now applied consistently everywhere.

Also fixes > to >= in SIMD stride checks across all files, so that when dims equals exactly the stride length, we use the SIMD path instead of falling through to scalar.
