Use a fresh virtual environment for each run.

If libcuopt-env exists, python -m venv libcuopt-env preserves previously installed packages. Delete it first or use python -m venv --clear libcuopt-env.

In `@ci/test_wheel_cuopt.sh` at line 34, Update the virtual-environment setup in
the test script to ensure libcuopt-env is fresh on every run, either by clearing
it before creation or using the venv command’s clear option while preserving the
existing environment name.

Replace assert with an explicit failure.

Python disables assert when python -O or PYTHONOPTIMIZE is active. The smoke test can then pass without checking libcuopt.load_library().

In `@ci/test_wheel_cuopt.sh` at line 42, Replace the assert-based check in the
libcuopt smoke test with an explicit runtime failure when
libcuopt.load_library() returns None, so the validation remains active under
optimized Python execution.
