ci(agents): reuse published agents image pins

[gregkonush]

Summary

• Renames the agents-ci image classifier away from Jangar terminology and classifies services/agents/** plus Agents smoke/deploy helpers as local-image changes.
• Resolves published control-plane and controller smoke-test images directly from argocd/applications/agents/values.yaml instead of downloading a Jangar release contract.
• Teaches the Agents smoke harness to accept separate immutable control-plane and controller image repository/tag/digest pins.
• Adds resolver/workflow regression tests so agents-ci keeps using Agents GitOps image pins for chart-only smoke runs.
• Aligns stale Torghut whitepaper scheduling assertions with the current manifest values exposed by the required full packages/scripts CI gate.
