/* test_notif_center.c — M7.3 通知中心内层迁 SDK 控件（宿主验证）。
 *
 * 复现 notif_center.c M7.3 SDK 路径所建控件集（meow_listview 虚拟化 vsource + set_item_draw 行自绘 +
 * set_empty_text 空态 + set_swipe_delete 左滑删除 + 双 meow_slider + meow_switch + 自定义画布 chip），验证：
 *   P1 listview 渲染通知行：行卡非背景像素（图标/标题/正文）+ set_item_draw 命中（含滚动换算）；
 *   P2 空态：count==0 且 set_empty_text 设了 → 视口内居中画文案（非背景像素）；
 *   P3 左滑删除：begin/move（超阈值）/end → on_delete 回调恰一次 + swipe 状态复位（撤销回调不触发）；
 *   P4 滑条/开关：meow_slider_set/get 与 meow_switch_set/get 往返一致（值写回控件）；
 *   P5 自定义画布 chip：meow_widget_rect 取几何 + render 出非背景像素 + meow_widget_hit 命中（owner 闸门开）。
 *
 * 几何/控件创建与 notif_center.c「M7.3 SDK 路径」镜像（owner 钉 NCP_WIDGET_ACT；行高 NCP_ROW_H）。
 * 注：宿主不含 launcher sb_icons / s_ui_theme / g_rows，故行/芯片用 meow_ui_text + 简化绘制复现契约；
 * notif 行自绘函数体（ncp_lv_row_draw）依赖 launcher 全局，真机由 notif_center.c 提供。
 *
 * 编译（在 patch_v2/meow_launcherd 下，宿主 gcc）：
