feat(meta-compile,meta-decompile): поддержка типа Enum (Перечисления) (v1.51/v0.42)

13-й тип. Рерайт Emit-EnumProperties на общие хелперы (был легаси-хардкод:
Comment/UseStandardCommands/ChoiceMode/формы/презентации/ChoiceHistoryOnInput).
Emit-EnumValue + comment; Parse-EnumValueShorthand больше не стрингифаит synonym
(строка|{ru,en}). Декомпилятор: снят гейт +Enum; захват EnumValue (values,
короткая строка|объект name/synonym/comment); StandardAttributes register-style
opt-out (блок Order/Ref present 85%, absent → standardAttributes:"").

Class-2 фиксы дефолтов (тип-зависимые, декомпилятор зеркалит компилятор):
- useStandardCommands: у Enum дефолт false (не true)
- quickChoice: у Enum дефолт true (не false)
- пустой <Synonym/> значения ≠ авто-синоним → synonym:"" (аналог object-level фикса)

ПОЛНЫЙ КОРПУС 2545 (acc+erp): match 2545/2545, TOTAL 0, 0 крашей — byte-exact,
order-preserved (сверено с реальными 1С-файлами modulo trailing newline+GUID).
Регресс 50/50 ps1+py, ps1==py identical. spec §7.3, кейс enum-full.
