Model API Owners and users with ManageModelCollaborators can change visibility. This updates the first-class `visibility` field only. It does not write Everyone collaborator rows or change `access.isPublic` on the v1 payload. Public still requires every caller to authenticate. Central config `com.cerebro.domino.modelmanager.allowPublicModels` blocks Public only; Discoverable and Private remain available when that setting is false.
