Pinned vision ids rot silently (glm-5v-turbo was retired from the Coding Plan endpoints while still valid on pay-as-you-go), so name the data behind the new pin — the only image-capable GLM id on every Z.AI surface — and why the pin cannot simply be dropped in favour of ProviderProfile.default_vision_model() (ZaiProfile returns None, which would route vision to a text-only chat model).
