Run #5 surfaced 6 collection errors in unsloth_zoo's tests/ that import
unsloth_zoo.saving_utils or unsloth_zoo.temporary_patches at module scope.
unsloth_zoo/__init__.py:314 raises ImportError("Please install Unsloth via
pip install unsloth!") unless UNSLOTH_IS_PRESENT is in os.environ.
Normally unsloth.__init__ sets that env var when unsloth is imported first.
In this job we go through the unsloth_zoo conftest device_type spoof first
(which loads device_type standalone, never running unsloth_zoo.__init__),
then later imports of unsloth_zoo.saving_utils trigger the real __init__
without the env var.
Fix: set UNSLOTH_IS_PRESENT=1 at the job-level env block. Has no effect on
unsloth itself.
