Description

Description

We did some work recently to cut down PyTensor import time. We should protect against unnoticed regressions by testing explicitly. Not sure this can be done inside a pytest/python environment or if we need a custom job in the CI for it that makes use of python -X importtime command

Research direction

Review the existing pytest and CI setup, then investigate Python's -X importtime entry point for measuring PyTensor import time. Decide whether the regression check belongs in pytest or a dedicated CI job; done means import-time regressions are detected automatically.
