AskaEth 2e8fac2a07 sdk(ui): 字符串资源外置(i18n 雏形 §13)—— meow_str_* + 内嵌双语表 + TF 覆盖表 + 控件接入
公开 SDK 前把 SDK/App 硬编码文案外置:新增 meow_str/meow_strf/meow_str_set_locale/
meow_str_locale,按当前 locale 取串(永不 NULL),第三方开发者可做多语言。

- 新增 include/meow_ui_str.h + meow_ui_str.c:取串优先级 = TF 覆盖表 > 内嵌当前语言
  (en_us→en 其余→zh) > 内嵌内置默认(zh_cn) > 原样返回 id。内嵌双语表(common.* 21 条 +
  ime.* 9 条);热路径零 malloc(编译期静态表 + ≤256 静态覆盖数组);纯 libc 宿主可单测。
- locale 存系统设置 settings.conf 的 ui.locale(默认 zh_cn,首次调用惰性读取);
  meow_str_set_locale 即时切换 + 重载覆盖表 + best-effort 持久化(流式改写保留其它行)。
- TF 覆盖表 MeowData/<pkg>/strings/<locale>.txt(id=text 行,UTF-8,'=' 两侧去空白);
  无卡/无文件/无该 id → 回落内嵌。meow_strf 用调用方缓冲(snprintf 语义,重入安全)。
- SDK 控件接入:dialog 默认按钮 OK/CANCEL + INPUT 占位、IME 键面/徽标(空格/确定/拼英/
  ?123/清/拼音/(无候选)/中)改走 meow_str;空态/加载态给 App 提供 common.no_data/loading。
- 测试:新增 test_meow_ui_str.c(内嵌回退/TF 覆盖优先级/未知 id 回退/切 locale 即时生效/
  查找正确性/meow_strf,tmp+env 两模式);全量宿主回归(widgets/dispatch/box/anim/scroll/
  listvirt/theme/ime_fix/pinyin/overlay/notif/sdk_input_keys/p1p2p3/config/vol/sb_collapse/
  notify_*) 0 回归;交叉 zig-mipsel -Wall -Wextra 0 warning。
- 文档:MEOW_APP_SDK.md 新增 §13(字符串资源/i18n,遗留顺延为 §14);docs/APP_DEV_GUIDE.md
  新增 §7.11。各宿主 test_*.c 头注释补 meow_ui_str.c 编译依赖。

边界(§13.7):仅 zh_cn/en_us 整串取用;不做复数规则 / BiDi / RTL / 动态字体回退(雏形)。

/* test_meow_ui_listvirt.c — 宿主验证 §5.5 虚拟化列表(W_LISTVIEW pool 模式):
* T1 虚拟化正确性:10000 项滚动窗口内容正确(hit 行号映射)/ bind 次数有界(全量扫过=count)/
* 回滚不重绑(scroll 回顶 bind 计数不变)。
* T2 多行富 item 渲染:双行(标题+副标题)/ 单行(仅标题)/ 左图标占位 / 右尾件 /
* 副标题超宽截断(不越过操作区)。
* T3 段头占位行(bind 返回 section=1)+ 空态占位(count=0 置 empty_text)。
* T4 完全自绘(set_item_draw 覆盖默认 renderer)。
* T5 焦点(tap_at → meow_ui_focus_owner)+ fling 联动(meow_scroll_wrap 包裹 pool 列表,
* track+fling 吸附到行边界;滚动只改 viewport 偏移)。
*
* 编译(宿主 gcc,链真实 gfx/sys/theme/vol/log/widget/input/activity/dialog/ime + 打桩 font/global):
