DeepSeek Harness Architecture Advisor Plugin

The `dsh-arch-advisor` plugin released by DeepSeek Harness (DSH) aims to address the issue of models providing generic advice based solely on memorized knowledge. By accessing open-source knowledge bases in real time, the plugin offers concrete methods, templates, and case studies for architectural design. Its core features include seven tools organized into three groups: lookup (e.g., search and read), design (e.g., guiding requirements clarification and generating ADRs), and documentation (e.g., specification skeletons and version management). The plugin supports end-to-end guidance from solution conception to documentation output, enabling users to describe their needs in natural language without memorizing specific tool names and still receive systematic design support. After installation, it requires an internet connection and a minimum DSH version of 0.1.2-rc.1.
