Detailed Description

dem — portable POD types + math + analytic SDFs shared by the Kokkos kernel ports.

Replaces the CUDA-only float3/float4 vector types and the host/__device__ helpers in math_utils.cuh / shapes/sdf_analytic.cuh with backend-agnostic equivalents (KOKKOS_INLINE_FUNCTION, usable on host and any Kokkos backend). The math is a faithful copy of the CUDA versions so ports reproduce the existing behaviour exactly.
