[plan] Document add-label safe-output capability in create-agentic-workflow.md #29047

Objective

Clarify add-label safe-output capability (or lack thereof) in .github/aw/create-agentic-workflow.md to guide Backend/QA engineers who naturally want to apply labels as workflow output.

Context

From agent persona exploration discussion #29038, there is no explicit add-label safe-output documented. Users may not know whether to use update-issue with a labels array, or if a dedicated label operation exists.

Approach

1. Investigate what safe-output tools are available for label operations (check safeoutputs --help and existing safe-output implementations)
2. If add-label (or equivalent) is supported: add it to the safe-outputs section with a example
3. If label application requires update-issue with a labels array: add an explicit note showing the pattern with safeoutputs update_issue --labels
4. Mark direct gh issue edit --add-label as an anti-pattern if not already present

Acceptance Criteria

• The safe-outputs section clearly documents the recommended approach for applying labels
• Includes at least one correct example showing label application
• Anti-pattern (direct gh CLI) is noted if not already present
