dsh-xiaohongshu-viral-note: Distribute Red's viral note Skills via DSH plugin

`dsh-xiaohongshu-viral-note` is an MIT-licensed DSH bundle plugin maintained by xuboboo, designed to simplify the workflow for handling Xiaohongshu viral notes within DeepSeek Harness. This plugin packages skill sets, reference documentation, scripts, and publishing constraints together, resolving the issue of manual capability assembly. Once installed, it registers a skill provider in `ctx.skills`, supporting features such as trending note research, topic selection, copywriting generation and rewriting, compliance verification, account weight analysis, scan-to-login, and controlled publishing. Users can install and enable it by running `dsh plugin add` and restarting DSH. Although the plugin itself does not depend on Python, the execution of its scripts requires Python.
