+What changed in `0.2.0`:
+- GitHub URL scans now download repo archives instead of cloning full git history.
+- Private GitHub repo URLs work when `GITHUB_TOKEN` is configured.
+- HTML reports now include hotspot summaries and interactive issue filters.
+- JSON report export and `--fail-under` make the CLI usable in CI.
