WHY IT NEEDS A POLICY

Why volt_set_budget_alert needs a policy

This tool creates or modifies configuration/state (budget thresholds and alert rules) reversibly. While it doesn't directly move money, it writes alert settings to a system used for financial spend tracking. Severity is medium: misconfiguration could suppress alerts and mask cost overruns, but cannot directly execute payments or delete data.

From the tool's definition volt_set_budget_alert sets a budget threshold and configures alerts; described as 'Set a budget threshold for daily, weekly, or monthly spend. Alerts when exceeded.' This creates and modifies alert configuration state in a system tracking AI spending.
