Release build logs

GitHub-sourced services now surface their CI build status and logs directly in Ryvn. The releases page, the install activity card, and the Automated Releases settings card all show a live build indicator with elapsed duration and the failing step name when something breaks. Expand any build to open its full GitHub Actions output inline, timestamped, color-coded by severity, with per-step attribution. Failed builds auto-expand so you land on the error without a click.
