+//! `sessions list` / `logs` / `diag`：读 M18 的会话索引与 JSONL 事件流。
+//!
+//! 数据源形状见 `DevDocs/SubAgentsTalk/launch-接口约定.md` §2/§5：
+//! - `<sessions_root>/game/index.jsonl`：一会话一行摘要（同 id 取最后一行，倒序）；
+//! - `<sessions_root>/game/<id>.jsonl`：事件流（`kind` + `payload`）。
+//!
+//! `diag` 把「退出信号 + stdout/stderr 文本」喂给 M15 的内嵌规则集，输出结构化结论。
