阶段四收尾：面板两行布局（row/expand/fill）+ 英文输出 + 混淆名对照表
- ViewInstaller：用 Table.row()/Cell.expand()+fill()/setFillParent 排出" 按钮一行、可滚动文字区一行"的面板；修掉把 setDebug 当成 setFillParent 的误用 - Scene2dPanel：按钮 isChecked/setChecked 与 Label.setText 改用对照表定名， 修掉"点一次反复触发"与"文字不刷新"两个 bug - SceneReader：面板输出改英文（编辑器缺中文字形，中文会渲染成方块） - 新增 tools/obfmap/MapMethods.java：载荷 vs 上游 libGDX 的字节码指纹比对工具 - 新增 混淆名对照表.md：类/方法/字段映射、推导办法、已踩的坑、验证状态
