阶段四：Spine 3.8.99 编辑器里挂上自建视图面板
目标：在 Spine 编辑器窗口内部加一个自己的视图面板（按钮 + 文字显示）， 点击读取场景对象，并像原生面板一样出现在 Views 菜单、可停靠可折叠。 本轮打通： 1. 编辑器在我们自己的进程里完整启动 - 类加载器必须是 URLClassLoader 本身（自检要求） - Editor.main 必须在 AWT EDT 上调用 - jvm.cfg 第 21 行要以两个空格结尾 + -DSpineJava - Editor.D:I 版本号、fonts/、/tzax 资源、Java8 版 launcher.Launcher 替身 2. 3.8.99 全量解密 → 可读源码 - 字符串 17251/17461（伪造同名调用帧对齐 key） - 混淆动态派发还原 53871 处（调引导方法取 MemberName） 3. 自建视图 - agent 在内存里给 us 枚举加 spineView 常量（不改磁盘，避开完整性自检） - 面板 Actor 由外部反射填进 us.spineView.D - 复用已有图标做别名（不新建图片资源） 最终 "Spine View" 出现在 Views 菜单，可与 Tree 并排停靠、折叠展开 另外： - ViewPatcher/ViewAgent：视图枚举与面板挂载的字节码插桩 - DecAll/ObMap/rewrite_source：字符串解密、派发还原、可读源码生成 - 阶段四-视图面板挂载.md：完整记录做法与踩过的坑 不纳入版本管理：rea/（独立仓库）、tools 下的 JDK/Ghidra 工具链、 Spine.app 与 spine-lab 副本、从载荷派生的批量产物。
