Mutation.publishDraftTheme
Promote a draft theme (role='unpublished' with parent_theme_id set) into the live 'main' slot for its store, demoting the previous main to 'unpublished' as a one-click backup. Snapshots the draft into theme_versions before swapping so the change is auditable + rollback-able.
