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. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

## Intel oneAPI version with oneMKL (Optimized for performance)

## Using sequential MKL (OpenMP disabled for better single-threaded performance)

## Added -lifcore for Intel Fortran runtime and -limf for Intel math library

## Aggressive optimization flags:
|
|
## -O3: Maximum optimization
|
|
## -xHost: Optimize for the host CPU architecture (Intel/AMD compatible)
|
|
## -fp-model fast=2: Aggressive floating-point optimizations
|
|
## -fma: Enable fused multiply-add instructions
|
|
## OpenMP re-enabled for MPI+OpenMP hybrid parallelism (MKL stays sequential to avoid nested parallelism)
