Subject: [PATCH] [CI][Diag] Dump numpy/scipy/openblas state pre-pytest

CI is hitting non-deterministic SIGSEGV crashes that look like the
OpenBLAS atfork regression tracked at numpy#30092 and scipy#23686.
The hypothesis is that the Isaac Sim base image rotated on
2026-05-12 picked up a scipy>=1.16.2 wheel whose bundled OpenBLAS
registers a buggy atfork handler.

Without knowing the actual numpy/scipy versions inside the pinned
test image, we can't confirm the hypothesis or pick a remediation
version.  This adds a small diagnostic print right before pytest
that emits:

  - pip show numpy scipy
  - numpy.__version__ / scipy.__version__
  - the on-disk filename of the bundled libscipy_openblas*.so

so the GitHub Actions log captures the actual deployed versions
for every test job.  The output is a few lines of plain text, no
artifacts, no impact on test execution.
