[extension] Add SpecJudge extension to community catalog (#4079)

* Add SpecJudge extension to community catalog

Add specjudge extension submitted by @JoaquinRuiz to:
- extensions/catalog.community.json (alphabetical order)
- docs/community/extensions.md community extensions table

Closes #4068

* Revert unrelated formatting-only edits in community catalog

Restore the compact single-line `tools` array formatting for existing
extensions that were incidentally expanded, keeping the diff scoped to
the SpecJudge addition and the catalog `updated_at` bump.
