② 单源 codegen 落地:
- strings.json 补全 lists 段(days7/featsFree/featsPro/featsTeam),
之前 extraction 漏了 4 个 List<String> getter;现 246 getter+4 list+5 method×6 语。
- design/codegen/gen_l10n_dart.mjs:strings.json → strings_{zh,en,ja,ko,ru,es}.dart,
getter 转义 \$、method 保留 $var 插值,dart format 定型(保证漂移闸零 diff)。
- app_text.dart 保持手写(enum/abstract 声明/AppLangMisc 逻辑),编译器强制 concrete⊆abstract 兜底。
- 往返无损:生成的 Dart 重新抽取 == strings.json 逐字节一致;flutter analyze 0 issue、flutter test 244 全绿。
