dsh-camp-safety: Camping Safety Response Plugin

The DeepSeek Harness (DSH) plugin `dsh-camp-safety` is designed specifically for outdoor survival scenarios and provides a pure Node.js implementation of camping safety contingency solutions. It depends on `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`, and once installed, it can return practical safety recommendations based on input parameters. Developers should note that it runs with the permissions of the current process, and it is recommended to inspect the source code and license. As a lightweight auxiliary tool, it offers convenient wilderness safety knowledge support for AI agent developers.
