refactor: rawptr[T] -> T*（R14）+ 修 REnum 前向占位未就地填充

R14：rawptr[X] -> X*（56 文件 / 834 行改动）；保留 6 处 rawptr[t.CPtr]（存纯裸指针的规范例外）。 修复：class X(t.REnum) 的变体字段写成自引用 X* 时，字段解析在变体扫描期经 ensure_forward_class 建了一个 opaque 前向占位；末尾 register_struct 按 Ty 指针去重会再建第二个同名 entry，而 find_struct 取首个（占位，0 字段）→ X.__sizeof__() == 0，报「已注册但大小为 0（字段链表未填充）」。改为注册前若命中同模块前向占位则就地填充（与 ensure_forward_class 文档口径一致）。TPC 无此问题，属 TPV 侧缺口。 验证：自举三重重编 SUCCESS；全量 77/77 顺序回归通过（修复前卡在 LLvmLiteTest）。
