cai-mh/dsh-sysbrief: System Understanding Briefs and Delivery Packaging Workflow

The DSH Harness plugin `cai-mh/dsh-sysbrief` aims to automate the process of extracting system context from unstructured PRDs or PDF documents and generating structured deliverables. The plugin provides core functionality for parsing documents, performing batched follow-up clarification questions, producing Markdown briefs, and packaging deliverables. It addresses the risk of missed details in manual summarization and offers agent developers a standardized development pathway. The plugin runs with DSH process privileges and depends on `cordis.patch.yml`; inspecting the source code and license is recommended before installation.
