Keep every primary handoff entry aligned on the first runnable verification command

Constraint: Restrict this checkpoint to handoff documentation consistency only
Rejected: Leave delivery handoff behind the newer restart guidance | All primary restart entrypoints should expose the same first verification command
Confidence: high
Scope-risk: narrow
Directive: Keep the first runnable command identical across AGENT, README, session handoff, and delivery handoff
Tested: Rechecked relative links in the updated delivery handoff and changelog docs
Not-tested: No code or training path executed in this handoff-consistency checkpoint

+## 2026-06-02 delivery handoff 同步最短可跑命令 checkpoint
+
+完成项：
+- 已把最短可跑命令同步到 `docs/delivery-handoff-2026-06-02.md`。
+- 现在 AGENT / README / session-handoff / delivery-handoff 四处入口已一致。
+
+结论：
+- 新 session 无论先看哪个主要交接入口，都能立刻拿到第一条验证命令。
