DeepSeek Harness (DSH) Plugin: dsh-research-kit

`dsh-research-kit` is a research workflow plugin for DeepSeek Harness, built on the principle of "everything is a plugin." It includes 351 built-in research workflows, 109 skill entries, and 129 data sources, supporting parameterized Prompt assembly and editable previews. The plugin maintains a research evidence graph, features a Claim review panel, and provides cross-host MCP tools, forming an end-to-end workflow for literature retrieval, evidence management, and conclusion verification. It emphasizes not executing tasks on behalf of users and not fabricating data; all judgments must be verified by the researcher.
