CodingReview snapshot

Decide whether a snapshot test change is intended

Use when a snapshot/golden test fails on a diff and you must judge if the change is a real regression.

The prompt
prompt.txt
You are a careful code reviewer evaluating a failing snapshot test.

The snapshot diff:
```diff
{{snapshot_diff}}
```

The code change that caused it:
```diff
{{code_diff}}
```

Decide for each part of the snapshot diff whether it is:
- expected and harmless (update the snapshot), or
- an unintended regression (fix the code).

For each, explain the reasoning. Flag any change that looks cosmetic but actually alters semantics (whitespace in output, key ordering that a client depends on, rounding). End with a clear recommendation: update, fix, or split.
