dsh-fridge-buy: Fridge Buying Plan Generator

The "everything is a plugin" philosophy of DeepSeek Harness (DSH) aims to provide agents with domain-specific deterministic logic. dsh-fridge-buy, a DSH plugin maintained by uckkk, focuses on refrigerator purchases and provides the `fridge_buy` tool, which returns purchasing recommendations through structured parameters. Open-sourced under the MIT License, it is suitable for scenarios requiring quick home appliance decision support, and developers can install and use it via terminal commands.
