multiplayer-todo.md and multiplayer-next.md tracked overlapping information in two places. Fold everything into multiplayer-next.md (architecture decisions, wire format, task breakdown with checkboxes, gotchas list, testing notes) and delete multiplayer-todo.md. Section numbers are unchanged, so existing code comments citing them by section/task number still resolve; update every such reference to point at the new filename.
