fix(HandlesImports): 跨模块 class_members 展平同步按继承源去重

81ad712 只同步了 HandlesClassDef(运行时) 与 DeclarationGenerator(stub struct)，遗漏并行 worker 跨模块重建路径 _EmitExternalClassDeclLlvm：仍用旧拼接+按字段名过滤算法，菱形继承下与 stub struct 布局不一致，worker 中 this_adjust 算不出偏移，继承方法 self 不调整，运行时错位崩溃(register_reexport 写 0x3f)。改为递归按继承源去重，与 HandlesClassDef._FlattenInherited 一致。
