activate snapshooter_strict_mode (#286)

CI/CD: Fix wrong snapshooter path.

Snapshooter was incorrectly searching for snapshots under /_/ on all operating systems. This was resolved on Linux and Windows by creating a symlink to /_/ or [Drive]:/_/. However, macOS does not permit this symlink, so I have decided to skip tests on macOS for now and prioritize other issues.
