feat(task): 创建任务可选下发种子意图,worker 免等首轮规划直接开跑

新增 seed_first_intent(默认开启):创建即把"描述+目标"作为一条意图
写入 frontier,worker 轮询领取立即执行,省掉开跑前的首轮 planner LLM;
跑完由 NotifyDone 正常唤醒 planner 判定/补充。CTF 场景常一 work 解决。

- Engine.Run 首轮 kick 改为"frontier 为空才触发",一处覆盖普通/种子/恢复三种情况
- HTTP createTask 与 spawn_task 工具同步支持;bump 工具 schema 刷新 flag 使旧库生效
