-E2E integration tests for the `pkgmgr mirror` command family.
-
-Covered commands:
-
-  - pkgmgr mirror --help
-  - pkgmgr mirror list --preview --all
-  - pkgmgr mirror diff --preview --all
-  - pkgmgr mirror merge config file --preview --all
-  - pkgmgr mirror setup --preview --all
-  - pkgmgr mirror check --preview --all
-  - pkgmgr mirror provision --preview --all
-
-All commands are executed via the real CLI entry point (main module).
-With --preview enabled, all operations are non-destructive and safe
-to run inside CI containers.
