dsh-taxi-fare: Taxi Fare Estimation

The core design philosophy of DeepSeek Harness (DSH) is "everything is a plugin." dsh-taxi-fare is a local taxi-fare estimation plugin maintained by uckkk. It allows users to calculate taxi fares precisely based on specified parameters locally, without requiring an internet connection, making it suitable for offline scenarios or use cases with low real-time requirements. Users can install and invoke it directly via command, and it runs with the current process's permissions.
