- Replace docker-reproducible.yml with reproducible.yml which produces
three artifacts per arch: Docker image, binary tarball, and AppImage
- Use a single multi-arch index digest in Dockerfile.reproducible as the
sole version tag to maintain; Makefile and CI no longer carry their own
per-arch image references
- Add packaging/appimage/ template (AppRun, .desktop, lighthouse.svg)
