feat(simd): add canonical hpc::simd module with runtime dispatch#3
Merged
Conversation
Add include/hpc/simd.hpp as the unified public SIMD module: - SIMDLevel enum and runtime detection (SSE2/AVX/AVX2/AVX512) - AlignedAllocator and aligned_vector for SIMD-aligned memory - SimdVec<T, Width> wrapper types with platform-specific specializations - Runtime-dispatched kernels (add_arrays, dot_product, scale, clamp) Refactor examples, benchmarks, and tests to use the new seam. Include OpenSpec change documentation for the deepening work.
