docs(hygiene): таблица владельцев файлов — в ARCHITECTURE, не во входе (#680)

Предыдущий коммит перенёс таблицу классификации файлов при сборке
(HP-1465-01) из ARCHITECTURE в SCOPE.md › Standing rule, а SCOPE — первый файл
обоих маршрутов входа: +211 слов маршрута автора и ревьюера — ровно перенос,
которого задача не допускает. Правило остаётся в SCOPE, таблица — в
ARCHITECTURE › Integration WS API › Files. entry-cost: автор 5 196, ревьюер
4 074.
