Misspell? s/Server/NewServer

[Peefy]

Besides, U can use schema single inheritance:

schema NewServer(frontend.Server):

[Peefy]

change konfig/appops/guestbook-frontend/test/main.k as follows:

import base.pkg.kusion_models.test.frontend as testFrontend

appConfiguration: testFrontend.Server {}

Becase files in kcl.yaml are seen as the same package, where the frontend package alias is overridden.
