Why oc_set_budget needs a policy

This tool modifies configuration data (budget goal) in a reversible manner. While it affects financial planning for a collective, it does not directly move money, commit financial obligations, or delete data. The blast radius is moderate: misconfiguration could mislead financial reporting or resource allocation, but the operation can be undone by setting a different budget.

From the tool's definition Tool name 'oc_set_budget' combined with description 'Set the yearly budget goal for a collective' indicates a create/modify operation that changes a collective's financial planning parameters.
