TermiNexus 9f396f4874 refactor(gen): 完成 P6 机械化迁移——Handler 类并入 Gen Mixin，语句实现单层化 
- 10 个 Handler 类主方法迁入 Gen：Assign/AnnAssign/AugAssign→AssignGenMixin，
  If/While/For/Return→StmtGenCifMixin，Match→新建 MatchGenMixin（注册 Generator MRO），
  Imports→ImportsGenMixin；方法体 self.Trans→trans，签名加 trans 首参
- 分派改：StmtGenMixin.translate_stmt 同链 self.translate_xxx + 跨链经 Handles 委托壳
  （NoVTable 静态绑定约束）；ExprCall 分派改走 ExprCallCall 壳
- 清理：HandlesTranslator 删 11 个 Handler 字段与 _init_state 创建段；
  StmtGenCifMixin 删 5 个 NewXxxHandle 工厂；main/BuildPipeline 补 HandlesAssign._g_gen 注入
- 委托壳保留：跨 Mixin 桥（Assign/AnnAssign/AugAssign/Match/Imports）待编译器缺陷修复后删

# Generator - 生成器（P1 骨架 + P2 多继承 Mixin 组合）
#
# 对象化重构宿主（wiki/14-oo-refactor.md）：
# @t.NoVTable + 多继承（BaseGen 状态 + TypeGen 类型映射），方法沿
# MRO 直接调用（Viper 多继承已支持，M1-M4）。后续 P3-P6 追加
# StructGen/ExprGen/CallGen/FuncGen/ClassGen/StmtGen/ImportsGen Mixin。
#
# 注意：Viper NoVTable 继承只合并字段、不转发父类方法符号（子类调
# 父类方法 mangle 成子类名 → undefined reference），因此字段初始化
# 全部内联，不调用父类 Init* 方法。
