Call when the user wants a visual overview rather than a narrative answer ("show me this week", "chart for today", "next 12 months", "看一下图"). Returns an ASCII chart: `hourly` = 12 two-hour blocks of one day, `weekly` = 7 days, `yearly` = 12 months. The `hourly` mode emits the same hour-resolution scores as `intentions_ask_hour` and is gated behind the Pro subscription on the same terms — on the free tier it returns a `subscription_required` error whose payload suggests `weekly` / `yearly` chart modes or `intentions_ask_day` as alternatives. `weekly` and `yearly` are always free.
