Description
体验：all-cli diff 缺参只报 accepts 2 arg，不说先 snapshot
不重复 #58（schema 缺参）、#61/#64/#66（use 缺参）。
用户路径
- 根帮助有
diff：对比两份 status snapshot。 - 第一次试：
all-cli diff。 - cobra
ExactArgs(2)原先打accepts 2 arg(s), received 0。 - Example 才有
all-cli snapshot --json | all-cli diff before.json -。缺参路径不知道要先 snapshot。
建议改动
缺参时打印 want diff <snapshot-a> <snapshot-b>，并给 all-cli snapshot --json > before.json 示例。
本地 clone 已按此改了一版（未 push / 未开 PR）。

Research direction
Start at the Cobra definition for the all-cli diff command and its ExactArgs(2) validation. Reproduce all-cli diff, then inspect the existing snapshot example. Done means missing arguments show the requested snapshot inputs and the all-cli snapshot --json > before.json example.
