fix: 修复任务列表数字ID乱序和内存轮询导致滚动跳动

两个修复：

1. 任务列表数字ID乱序（#32）：新增 compareTaskIds 比较函数，纯数字ID按
   数值大小排序（1, 2, 3, 10 而非 1, 10, 2, 3），非纯数字回退到
   localeCompare 自然排序。listTasks 和 taskStateMessage 两处排序入口
   均已修复。

2. 终端 RSS 内存轮询引发滚动跳动（#31）：useRssDisplay hook 新增 isLoading
   参数，仅在加载中启用定时轮询，闲时仅渲染一次内存占用值，避免 Ink 重渲染
   干扰用户滚动查看结果。

附：TaskCreateTool.isConcurrencySafe 改为 false，防止并发任务创建的文件
IO 竞态。
