"""Regression coverage for #3283 profile/config import ordering.

Importing ``api.profiles`` before ``api.config`` used to trigger a circular import
through ``profiles._resolve_base_hermes_home() -> api.config``. ``api.config``
then caught the partial-module ``ImportError`` from its startup
``init_profile_state`` import, so the later config import never initialized the
sticky active profile.
