The AVX2 get_checksum1_avx2_64() read mul_one before initializing it, which is undefined behavior. Replace the cmpeq/abs trick with _mm256_set1_epi8(1) to match the SSSE3 and SSE2 versions. Add a TEST_SIMD_CHECKSUM1 test mode that verifies all SIMD paths (SSE2, SSSE3, AVX2, and the full dispatch chain) produce identical results to the C reference, across multiple buffer sizes with both aligned and unaligned buffers.
