Add MPI+OpenMP hybrid parallelism (48 ranks x 2 threads) for full 96-core utilization

Browse Source 
Enable OpenMP threading in finite-difference kernels (diff_new, diff_new_sh, diff_newwb,
lopsidediff, kodiss, kodiss_sh) with collapse(3) directives on 36 triple-nested loops.
Update build flags (-qopenmp), MPI process binding, and runtime configuration.
