feat(skd): placement в SelectedItemFolder (selection)

SelectedItemFolder (группа полей с заголовком в selection) имеет
<dcsset:placement> — может быть Auto/Horizontally/Vertically/Special.
Мы захардкоженно эмитили Auto, теряя non-default значения.

decompile: читаем placement, сохраняем если ≠ Auto.
compile: эмитим из item.placement (default Auto для bit-perfect-default).

PS и Py compile синхронизированы.
