WHY IT NEEDS A POLICY

Why create_nft_collection needs a policy

This tool creates NFT collections, which is a reversible write operation (collections can be abandoned or metadata updated). It does not delete data (not Destructive), does not execute arbitrary code with unpredictable side effects (not Execute in the dangerous sense), and does not directly move money (not Financial, though NFTs have value).

From the tool's definition Tool creates a new NFT collection with 'erc721' or 'erc1155' type. The verb 'create' and the function of establishing a new on-chain asset indicate a write operation that modifies state.
