/* 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）：
