/* test_meow_ui_swipe.c — 宿主验证列表行左滑删除（§5.5,M7.3 缺口 #9）：
 * T1 滑动手势判定与冲突消解：begin 命中可滑行返回 1；横向小位移 = swipe（move 返回 1 消费）；
 *    纵向大位移 = 滚动手势优先（move 返回 0 并取消本行 swipe）；非启用行 begin 返回 0。
 * T2 左滑超阈值 → 删除动画（meow_anim 滑出），结束后 on_delete 回调恰一次 + swipe 状态复位。
 * T3 未超阈值 → 回弹，on_delete 不触发，swipe_dx 回到 0。
 * T4 点按（无位移）：begin 后 end（未 started）返回 0（App 走 tap_at），不触发 on_delete。
 * T5 右露删除区像素：滑动中重绘列表 → 右露区画主题 error 底 + 行内容左移。
