I found some issues that need attention. Medium (P2): The image link in the changeset uses a leading slash which will likely break in the generated package CHANGELOG and on npm. Suggest pinning to a raw GitHub URL.

The image path starts with a leading slash. In the generated CHANGELOG for the 'roo-cline' package (as rendered on npm), this likely will not resolve. Pin to a raw GitHub URL for this commit for portability.
