- POST /api/tasks/<tid>/continue: 校验 auto 模式 + pending 非空, skip_seed 启动 - engine skip_seed: 跳过起始网址直接从缓存队列消费 (不重爬 seed, 不重复入 visited) - 关键修复: max_pages 原为累计上限(visited>=max_pages), 已达标任务无法继续; 继续模式改为按本次新增页数重新计算上限, 可反复继续直到缓存耗尽 - 详情弹窗 auto 任务且有缓存时显示 [⏩ 继续爬取（缓存 N 条）] 按钮 - 端到端测试: max_pages=2 链路 执行(seed+p1,缓存4) → 继续(p2,p3,缓存2) → 继续(p4,p5,缓存0) → 无缓存报错 ✅
