Why add_workitem_comment needs a policy

Adding a comment creates new data in Azure DevOps that persists and is visible to team members. This is a Write operation (reversible modification—comments can typically be edited or deleted). Severity is medium because unauthorized comments could be used for social engineering, misinformation, or spam within the DevOps system, but do not directly corrupt critical data or trigger destructive actions. Confidence is 0.
