- Gen 内部 1742 处 HandlesX.func() 改 self.Gen.Y.method() 链式调用 - 数据类/常量迁移 GenTypes.vp（10 类 + CLASS_META_*/META_*/SEQ_KIND_*/FIELD_MAX 等） - 管线/保留文件经 GenApi.vp 模块级入口（48 函数带类型注解，从 Gen 方法签名自动生成） - 删除 26 个纯委托 Handles 文件，仅留 5 个实体文件（Base/Translator/Expr/ExprCall/ExprCallTable） - 修复字段分裂：TypeGenErr CurrentFile/TraceCount 链式化；CallGenBase TempDir/Cexport 真源化
