协调者与蜂群模式：多 Agent 编排机制

Agent 是派人干活。
TaskCreate 是往白板上贴任务卡。
Runtime Task 是正在跑的人或远端人影。
Coordinator 是星型编排器。
Swarm 是有成员、有邮箱、有任务白板的团队。

Fix the null pointer in src/auth/validate.ts:42.
Session.user can be undefined when the session expires but the token remains cached.
Add a null check before user.id access; if null, return 401 with "Session expired".
Run validate.test.ts and report the commit hash.

Based on your findings, fix it.
