Keep one canonical RAGOps PR comment source

[thangldw]

Outcome

Prevent deterministic and statistical smoke workflows from racing to overwrite the same canonical RAGOps marker comment.

Change

The repository publisher listens only to RAGOps reusable gate smoke. The statistical smoke continues to enforce its check and upload bounded evidence, but it no longer competes for the canonical PR comment.

Evidence

• Ruff passed.
• 30 focused workflow and publisher tests passed.
• The race was observed on PR Ship the three-minute RAG regression proof #26 after both source workflows completed successfully.

Compatibility

Downstream publisher recipes already select one exact source workflow and are unchanged.
