dsh-hike-train: Generate Hiking Plans Based on Parameters

The `dsh-hike-train` plugin for DeepSeek Harness (DSH) is designed to provide hiking training plan generation capabilities for outdoor sports agents. Implemented entirely in Node.js with no network dependencies, the plugin is maintained by uckkk. Before use, ensure the environment dependencies `@deepseek-ai/cordis` (v4.0.1+) and `@deepseek-ai/dsh-tools` (v0.1.0-rc.6+) are satisfied. Users can install it with the command `dsh plugin add github:uckkk/dsh-hike-train`; after installation, the `hike_train` tool can be invoked to generate hiking plans. The plugin is released under the MIT license, and reviewing the source code before deployment is recommended.
