dsh-doc-review — DeepSeek Harness Web Document Review Dialog Plugin

The `dsh-doc-review` plugin resolves the cramped display of Markdown design documents in compact cards within DeepSeek Harness Web by upgrading them to full-screen modals. Core features include GFM support, code highlighting, math formula rendering, and inline comment management; interaction capabilities such as automatic pop-up, close-without-cancellation, and one-time locking; as well as Chinese/English internationalization and comment persistence. The plugin aims to improve the design review experience in plan mode and adaptive pipelines.
