WHY IT NEEDS A POLICY

Why create_wallet needs a policy

This tool creates new wallet addresses and private keys, which are reversible data creations (wallets can be removed, as evidenced by the sibling tool 'remove_wallet'). It does not execute transactions or move funds directly, so it is Write rather than Execute or Financial. However, severity is high because improper wallet creation or handling of private keys can enable unauthorized financial access and fund theft.

From the tool's definition Tool description states "创建新的钱包地址和私钥" (create new wallet address and private key). The tool creates new data (wallet and private key) that is stored and used for subsequent operations.
