dsh-earthquake: A Localized Decision Tool for Earthquake Evacuation Scenarios

The `dsh-earthquake` plugin for DeepSeek Harness (DSH) is designed specifically for earthquake emergency response scenarios, providing locally executed disposal steps that do not rely on network connectivity. Implemented in pure Node.js, the plugin registers tools that return key steps based on the given scenario. Installation is simple and requires only a single command to invoke it in a session. It is well suited to emergency scenarios with high requirements for fast response and offline availability. Users should note that first-aid content is for reference only and that the plugin runs with the permissions of the current process.
