PERF-2 P3: the batched device V-cycle microbenchmark — mg_vcycle.cu (masked variable-coefficient five-point red-black half-sweeps, residual, CSR restriction in a fixed order, prolongation, coarsest sweeps; [K][n] layout, blockIdx.y = march), LevelExport/export_hierarchy and vcycle_f32_reference on the CPU side, and the ignored cuda-feature test that checks the K = 1 device V-cycle against the CPU f32 reference and times K = 1 / 8 / 16 per march
