feat(parallel-agents): 子智能体禁派活/脚本(防模仿总控) + 面板能力完善

后端 parallel_agents.py：每个并行席位 excluded_tools 增加 agent_orchestration
(派活) 与 bash(脚本逃逸)，并在任务消息里加「角色边界」护栏——根治弱模型拿到
带「总控/业务链条」语气的任务后模仿总控输出「总控调度指令…」、绕道 glob/bash
翻找派活脚本的问题。新增 /api/parallel-agents/auth/token 取 token 端点
(auth/csrf 豁免)。

parallel-agents-vue 面板：协作澄清卡片、步骤图标/步骤展示、API 与类型完善等。
