Check Image Tags in Manifests

When to use it
Use before or after a deploy to confirm expected image references.
When not to use it
Do not rely on it if manifests are templated and the rendered output is the real source of truth.
Undo or recovery
No undo needed because this command is read-only.
Expected output
Unique image references such as image: registry.example/app:v1.2.3.
