WHY IT NEEDS A POLICY

Why update_board_item needs a policy

This tool modifies existing data (board items) but does not delete or irreversibly destroy anything. The effect is reversible—board items can be updated again or reverted. While it affects content visibility and organization within Looker boards, the blast radius is limited to that specific board item's metadata/configuration.

From the tool's definition update_board_item updates a board item, indicating a reversible modification of existing content within Looker's board management system.
