dsh-codeui: DeepSeek Harness Code Review Workbench

dsh-codeui is a code review workspace extension for DeepSeek Harness, designed to address the lack of a centralized entry point to view changes following AI's continuous code modifications. The tool provides a workspace resource explorer, a right-side Review panel, and a round navigation track. Core functions include displaying file diffs by round, supporting unified/dual-pane views, and exporting cumulative patches. It features IDE-like syntax highlighting and allows for direct editing of disk files within a safe scope. After each round of conversation, the plugin generates a Review card summarizing the number of modified files, lines, and paths, supporting hover details and click-to-jump navigation via the right-side track. It supports capturing various edit operations, scanning historical logs to complete details, and ensures all Git operations are read-only. The plugin is maintained as a static npm package and is available via GitHub.
