dsh-readme-forge: Automatically Generate READMEs for DeepSeek Harness Plugins

`dsh-readme-forge` is a plugin in the DeepSeek Harness ecosystem, designed to reduce the friction of manually authoring documentation. It extracts information from configuration files such as `package.json` and `cordis.patch.yml`, and automatically generates a standardized `README.md` that includes a title, description, and installation commands. The tool has zero runtime dependencies, operates in a read-only safety mode by default, and provides CLI and Agent interfaces. It enables rapid construction of documentation pipelines and, together with `dsh-llms-forge`, improves the discoverability of the plugin ecosystem.
