Detailed Description

flow — portable (Kokkos) Robust-Scaled cut-cell IBM primitives + per-cut-cell overlay build.

Kokkos port of cut_cell_ibm.cuh (the boundary-distance polynomials) and ibm_fill_entry from mac_ibm.cuh (the per-cut-cell stencil-modification factors K/M/X/Nbc/R + D_rescale). Faithful copy of the Dirichlet/Neumann, point-value(SCHEME 0)/cell-average(1), and sandwiched (double-sided) cases. Output factors are written into Kokkos Views (SoA, [list_idx*6+k]); the build kernel fills one entry per cut cell. KOKKOS_INLINE_FUNCTION so the math is shared with the host reference.
