KanbanRenderer.uncolumned.test.tsx 的两条断言都落在 React.lazy 边界之后,
而文件顶部只 import './index' —— 它仅登记 lazy 工厂,并不执行动态 import,
所以首次 import('./KanbanImpl') 被计入 RTL findBy 的 1000ms 有界窗口。

按 AGENTS.md §测试纪律,在模块作用域直接 import './KanbanImpl'(specifier 与
index.tsx:124 完全一致,ESM 按解析后的 specifier 缓存),成本进入 import 阶段,
不受任何 test/hook 超时约束。沿用 PR #3464 两个姊妹文件的写法。

+// 1000ms default, so without this the suite would race the module loader. The
