cwltool 3.2.20260720092025 ran successfully on RIKEN Fugaku 🇯🇵🎉🥳

It ran the CWL v1.0 conformance tests successfully, and also ran a small MPI workflow compiling (mpifcc) and running (mpiexec) on PJM.

cwltool CWL v1.0 conformance tests passed on RIKEN Fugaku HPC login node! Unfortunately, it's failing when using PJM (due to login / compute nodes using different CPU architectures). An interesting workflow problem 🤓
