WHY IT NEEDS A POLICY

Why prepare_relayer_approval needs a policy

This tool prepares a transaction that grants approval/delegation to a relayer for future minting operations. It creates or modifies an authorization record on the blockchain. While it enables future mints, the immediate action is writing an approval/permission record. It is reversible in principle (approvals can typically be revoked), so it falls under Write rather than Execute.

From the tool's definition Prepare a one-time Sui transaction where the user approves the configured relayer to mint SHIT to their wallet without approving every future mint.
