SetDocumentVariantsCommand class

class ew::core::SetDocumentVariantsCommand

Command that sets a document's alternate-variant state as one undoable step: the parallel alternate drafts, the name of the active variant, and the live body. Switching between variants swaps the live body with a stored alternative, so the three must change together; creating, renaming, or deleting a variant leaves the body unchanged (pass the current body). Undo restores the previous state and redo re-applies the new one. This owns the wholesale body swap of a variant switch (a structural change), separate from the editor's own incremental text undo.
