dsh-pack-skill: A Packaging Tips Plugin for DeepSeek Harness

The `dsh-pack-skill` plugin for DeepSeek Harness (DSH) is implemented in pure Node.js and is designed to generate packaging or relocation plans directly via parameters, without network dependencies. Maintained by the community, it is installed using the `dsh plugin add` command and depends on a specific version of the DeepSeek tool library. After installation, users can invoke the registered `pack_skill` tool in a session to execute local packaging logic, making it suitable for DSH workflow scenarios that require integrating this capability.
