When a backend installation fails (e.g., due to missing 'latest-' tag), try fallback URIs in order: 1. Replace 'latest-' with 'master-' in the URI 2. If that fails, append '-development' to the backend name This fixes the issue where backend index entries don't match the repository tags. For example, installing 'ace-step' tries to download 'latest-gpu-nvidia-cuda-13-ace-step' but only 'master-gpu-nvidia-cuda-13-ace-step' exists in the quay.io registry.

I'm ok with it temporarly now.
But you should do a follow-up to set the environment variables in core/cli/run.go where all the others are already defined, and propagate these as AppOption and pass the application to InstallBackend
