dsh-research-check: Deliverable Evidence Chain and Compliance Validation

`dsh-research-check` is a plugin in the DeepSeek Harness ecosystem, focused on compliance checks for deliverables (papers, documents, bid proposals, etc.). It converts requirement documents into executable specifications, verifies page counts, abstracts, citations, and numerical consistency, and generates traceability ledgers and audit metadata. It supports integration via CLI or the MCP protocol (such as Claude Code and Cursor), runs checks locally, and ensures data security.
