"""
Integration tests for the `pkgmgr config` command.

We only exercise non-interactive, read-only subcommands here:
  - pkgmgr config show --all
  - pkgmgr config show pkgmgr

Interactive or mutating subcommands like `add`, `edit`, `init`,
`delete`, `ignore` are intentionally not covered in E2E tests to keep
the CI environment non-interactive and side-effect free.
