dsh-publish-skill: XDSP Frontend Sequential Release Plugin

`dsh-publish-skill` is a DeepSeek Harness plugin designed to address the cumbersome version management and module publishing challenges in XDSP front-end projects. It provides the `/publish-skill` command, supporting full publishing, resumable publishing, single-module publishing, and unified version management. By strictly executing `yarn transpile` and `npm publish` in sequence and incorporating a manual confirmation mechanism, it ensures an orderly publishing process without side effects. Developers can quickly trigger the publishing workflow by specifying parameters, thereby improving development efficiency.
