- ENUM_MEMBER_MAX_LOCAL/RENUM_CLASS_MAX/RENUM_VARIANT_PER_CLASS/RENUM_ALIAS_MAX 补回 ClassGenEnum
  （未定义名在常量上下文折叠为 0 → 枚举成员收集被静默禁用 → register_enum 永不调用
  → EnumTable 恒空 → `OpKind.Add` 裸名 NameError，includes/ast/base.vp L241 根因）
- SPEC_CACHE_MAX 补回 ClassGenGeneric（原 HandlesClassDef 定义）
- VTBL_METHOD_MAX 补回 ClassGenVTable
- META_MAX/META_KEY_LEN 补回 ClassGenBase
