上一提交只补了 3 级路径 _try_resolve_nested_cdefine，而 win32file.STD_OUTPUT_HANDLE 是 2 级访问 → 走 _handle_attr_name → _lookup_cdefine，该函数只查 SymbolTable/_define_constants，没有裸名路径已有的 _all_define_constants 回退。includes 的 vpi 模块不会在 SymbolTable 里登记 IsDefine，于是解析落空 → _lookup_module_global 现造一个无定义的 @STD_OUTPUT_HANDLE → 链接期 undefined symbol。补回退（仅在无同名变量/全局时），覆盖 STD_INPUT/OUTPUT/ERROR_HANDLE。
