fix: spawn_workers skill 名称修正 — airplan → airplan-v2:do

skill 目录名是 airplan-v2，不是 airplan。Claude Code 按目录名注册。
正确的 Skill 调用格式为 Skill("airplan-v2:do")。

同步更新：
- eng_mode.py spawn_workers() 返回值
- commands/eng.md dispatch 操作步骤
- test_t_121_122.py 测试断言
- 设计文档 3.2.11b spawn_workers 伪代码

 2. 对 `taskIds` 中的**每个** `tid`，顺序执行：
    a. 读 `AirPlan/state/airarc/reviews/task-graph.json`，从 `nodes[tid].task` 取任务描述文本
    b. 调用 `Skill` 工具启动子代理：
-      - `skill`: `"airplan"`

    c. 每个 `Skill` 调用自动以 `fork_context=false` 运行，创建隔离的 Do Worker
 3. 所有 Worker spawn 完成后，进入 monitor 状态
 4. Worker 完成后，对其 `result.json` 调用 `--sub merge --result <path>`
