### What changes were proposed in this PR? When the `zero-shot-image-classification` task ran without at least 2 candidate labels, the operator raised the error from *inside* the per-row loop, so it crashed mid-run instead of failing cleanly. This moves the check up front, alongside the operator's other config validations, so it fails fast with a clear message before any rows are processed. Labels now come from the **Candidate Labels** field only (matching the text `zero-shot-classification` task); the old fallback that read labels from the prompt column is removed. ### Any related issues? Closes #7199 (the Part B follow-up to #7297, which addressed the same issue). ### How was this PR tested? Unit tests + the generated-Python compile check, plus a quick headless run of the generated operator: with 0 labels it now raises a clear "requires at least 2 Candidate Labels" error before the loop; with 2+ labels it proceeds normally. ### Was this PR authored or co-authored using generative AI tooling? Yes, this PR was co-authored with Claude in compliance with ASF policy. -- This is an automated message from the Apache Git Service.
