【中文说明】用于在Herdr环境下并行运行多个编码代理，完成任务拆分、独立工作树创建、环境隔离、状态监控、代码审查和合并。使用时先确认`HERDR_ENV=1`，再根据`herdr pane current`返回的代理类型配置子任务、文件简报和评审流程。 Run several coding agents in parallel under Herdr: stage decomposition, one git worktree, isolated env, pane and file brief per agent, state monitoring, review, merge. Child kind is read from `herdr pane current` (.result.pane.agent) and matches the orchestrator (omp, opencode, claude, codex, kimi, ...). Requires HERDR_ENV=1.
