+ * Hermes 群聊（Batch 3 §N）
+ *
+ * Hermes 内核没有「群聊」概念，由 ClawPanel 前端编排：
+ *   - 用户选择多个 Profile（每个对应一个 Agent 配置）
+ *   - 发消息时并发调用每个 Profile 的 hermes_agent_run
+ *   - 把每个 Profile 的回复以 @profile_name 标记后显示
+ *
+ * 限制：
+ *   - 仅 Tauri 桌面端（Web 模式禁用，因为依赖 hermesAgentRun）
+ *   - 非流式（用阻塞式 run 等所有完成）
+ *   - 不持久化（一次性会话，刷新清空）
