WHY IT NEEDS A POLICY

Why arkadiko_update_vault needs a policy

This tool modifies an existing DeFi vault's collateral or debt positions on the Stacks blockchain. While it is reversible in principle (positions can be re-adjusted), incorrect adjustments could expose the vault to liquidation risk, making the blast radius high. It falls under Write as it modifies existing data rather than irreversibly deleting it or directly moving money.
