dsh-kebabcase: A Pure Node.js Kebab-Case Conversion Plugin

`dsh-kebabcase` is a DeepSeek Harness plugin for converting camelCase to kebab-case locally. It is implemented entirely with Node.js, has no network dependencies, and is suitable for offline environments. Before installing it, the dependencies `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` must be installed. Once installed, developers can invoke this tool directly in conversations or scripts. Because the code runs locally, it is recommended to review the source code to ensure security.
