Post-deploy follow-up: resolved by fix-forward and superseding rollout.

Evidence:

• chore(jangar): promote image 46cf489e #5563 auto-merged the 46cf489e Jangar promotion, but its original post-deploy verifier run failed on an ancestry-fetch false negative after Argo had already synced a newer main revision.
• fix(jangar): fetch main before rollout ancestry check #5568 fixed that verifier race, and the follow-on chore(jangar): promote image 01717359 #5572 promotion verified the fixed path on current main.
• chore(jangar): promote image 01717359 #5572 post-deploy run 25404149517 passed with Argo Synced and Healthy at 30a5b4d1118b497ab8e483aa579dac391efe3303.
• Current live Jangar image is 01717359@sha256:a74d815597125bd164f7d4862af98e0f8bf1e50df765ace94d47b66566fb0f85; pods are ready with zero restarts.

Rollback:

• Rollback remains a GitOps revert of the latest Jangar promotion manifests. Revert chore(jangar): promote image 01717359 #5572 (30a5b4d1118b497ab8e483aa579dac391efe3303) to return to the previous known-good promotion.
