Also extend the compat scanner to catch datetime.UTC used as an attribute (datetime.datetime.now(datetime.UTC)) in addition to direct imports, so this form cannot be reintroduced undetected. Co-Authored-By: Zindello <josh@zindello.com.au>

"""Regression tests guarding against Python 3.10 compatibility breakage.

pyMC Repeater supports Python 3.10+ (LuckFox Pico Ultra ships with 3.10).

These tests scan the source tree statically so regressions are caught in CI

without needing a 3.10 interpreter in the test environment.
