fix(skd-decompile): сворачивать дефолтные auto selection/order группы в shorthand

После 6781bb3 компилятор кладёт в каждую группу структуры авто-поле выбора и
авто-порядок (SelectedItemAuto/OrderItemAuto), как делает платформа. decompile
сохранял их как selection:["Auto"]/order:["Auto"], из-за чего Try-StructureShorthand
не сворачивал цепочку и выдавал громоздкую объектную модель вместо строки
"A > B > details".

Теперь selection/order, состоящие ровно из одного "Auto" (предикат Is-AutoOnly /
is_auto_only), считаются дефолтом и не мешают свёртке. Round-trip снова bit-perfect:
shorthand перекомпилируется в идентичный XML (Parse-StructureShorthand сам добавляет
эти auto-поля). Отключённый auto ({auto,use}), смешанные списки и явные поля свёртку
не проходят и остаются в объектной форме.
