💡 需求背景和解决方案
树形结构表格选中子节点后收缩父节点，header checkbox 状态显示异常（应为半选，实际为空）。
根因：
useRowSelect.tsx中getSelectedHeader()仅基于可见行 (canSelectedRows) 计算状态。收缩时子节点从可见数据移除，但tSelectedRowKeys仍包含这些 key，导致intersectionKeys为空。修复：
isIndeterminate：增加条件intersectionKeys.length < tSelectedRowKeys.length（存在不可见的已选行）isChecked：增加条件intersectionKeys.length === tSelectedRowKeys.length（所有已选行均可见）📝 更新日志
