WHY IT NEEDS A POLICY

Why add_pr_comment_reaction needs a policy

This tool modifies state by adding a reaction to a comment, making it a Write operation rather than Read. However, the severity is low because: (1) reactions are non-substantive metadata with minimal blast radius, (2) the operation is explicitly idempotent and reversible, (3) there is no data deletion, financial impact, or code execution involved, and (4) misuse would only add harmless emoji reactions to pull…

From the tool's definition add_pr_comment_reaction adds an emoticon reaction to a pull request comment, which creates a new reaction record.
