- Add mpi_stub.h providing all MPI types/constants/functions as no-ops
(nprocs=1, myrank=0) with memcpy-based Allreduce and clock_gettime Wtime
- Replace #include <mpi.h> with conditional #ifdef MPI_STUB in 31 files
(19 headers + 12 source files) preserving ability to build with real MPI
- Change makefile.inc: CLINKER mpiicpx->icpx, add -DMPI_STUB to CXXAPPFLAGS
- Update makefile_and_run.py: run ./ABE directly instead of mpirun -np N
- Set MPI_processes=1 in AMSS_NCKU_Input.py

- Update makefile.inc with Intel oneAPI compiler flags and oneMKL linking
- Configure taskset CPU binding to use nohz_full cores (4-55, 60-111)
- Set build parallelism to 104 jobs for faster compilation
- Update MPI process count to 48 in input configuration
