Baseline is not VCS friendly

The baseline file is not VCS friendly, because it's a single-line JSON.
Please consider
* auto-formatting the file,
* ensuring the the contents are also sorted by something stable.

For example on the top level sort by their `name`, and the internal `trace` list should also be sorted by for example `traces.sort { "${it.owner}/${it.name}/${it.descriptor}" }`.

This will make multiple runs on the same project produce nice diffs/PRs as the project evolves.

Locate the baseline file and inspect how it is produced and serialized. Make the output formatted and stable by sorting top-level entries by name and each internal trace list by owner, name, and descriptor; done means repeated runs produce readable, consistent VCS diffs.
