WHY IT NEEDS A POLICY

Why create_gas_station needs a policy

This tool creates a new project/configuration for gas station fee sponsorship on the Aptos blockchain. 'Creates a new' indicates a Write operation (generating project files, configuration, scaffolding). While gas stations involve financial concepts (fee sponsorship), this tool appears to create a project/template rather than move funds or commit financial obligations directly.
