WHY IT NEEDS A POLICY

Why fcart_update_coupon needs a policy

This tool modifies coupon records (pricing/discount rules) within the FluentCommunity ecosystem. While coupons have financial implications, the tool itself updates coupon details rather than processing transactions or moving money. It is reversible (the original coupon state can be restored via another update). This places it in the Write category rather than Financial.

From the tool's definition Tool name 'fcart_update_coupon' and description 'Update coupon details' indicate modification of coupon data. The 'update' action is reversible and modifies existing data without deletion or financial transaction execution.
