DeepSeek Harness NPM Registry Management Plugin

`dsh-npm` is a web-enabled plugin for DeepSeek Harness (DSH), designed to provide agents with full NPM registry management capabilities. By invoking the official API and the local CLI, it supports querying package information, version verification, searching, as well as publishing and deprecating packages. The plugin also supports private package authentication and includes a web-based visualization panel. Users should note that publishing and deprecating operations are irreversible, and that tokens are securely stored. Maintained by `zhengjy01`, this plugin is suitable for developers who need to automate package version management and publishing within an agent.
