dsh-pot-base: Hot Pot Base Selection Plugin

The `dsh-pot-base` plugin for DeepSeek Harness (DSH) aims to address the pot base selection problem in hot pot gatherings. It is maintained by uckkk and belongs to the "Fun Dress-Up" category. By registering a tool named `pot_base`, it returns corresponding hot pot meal options based on input parameters without making external network requests. Users need to install the `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` environments and run the plugin with process privileges. The plugin source code is open, and the GitHub repository provides further information.
