Summary

• Replace the kubeconfig merge in infra-sync.sh with a Python helper while retaining infractl for artifact downloads.
• Name infra contexts after their referenced clusters and always prefix infra user names with the artifact cluster name; avoid silent cluster, user, or context collisions.
• Back up the prior kubeconfig and write the merged file privately, preserving it if the merge fails.

Supersedes #113.

Validation

• python3 -m unittest discover -s scripts/dev -p test_infra_sync_merge.py -v (5 tests)
• bash -n scripts/dev/infra-sync.sh
• git diff --check
