high-order multistep coupling for solid — fluid conjugate heat transfer

The cwipi-samurai mini-app couples two independent Samurai/PETSc solvers (a solid and a differentially heated fluid cavity) through ONERA’s Cwipi library to simulate unsteady, nonlinear solid-fluid conjugate heat transfer. It serves as a reference case for validating the high-order multistep coupling scheme in Cwipi, showing temporal order k+1 up to order 4, before it is used in an HPC context.
