 * would only remove the body marker — leaving an orphaned `w:footnote`
 * element in the notes part — this routes the removal through the document
 * API wrapper, which tombstones the note: the `w:footnote` element stays in
 * the part so undo restores the note text, and export prunes session-managed
 * ids that have no surviving reference (SD-3400).
 *
 * Plain orchestrator (no PM command plumbing) so any caller can use it; the
 * `deleteSelectedNoteMarker` editor command is a thin shim over this function.
