"""Conftest for opencode-openenv tests.

The env directory is named ``openenv`` which collides with the installed
``openenv-core`` namespace when pytest adds the parent directory
(``…/opencode``) to ``sys.path``. Strip the shadowing entries and evict
any already-loaded stale modules so ``import openenv.core`` resolves to
the installed package.
