dsh-edit-diff：在 DSH 文件变更卡片上重绘行级 diff
dsh-edit-diff 是 DSH 社区工作流插件，在 edit/write/insert/str_replace_editor 及 run_code（PTC）子调用的工具卡片上重绘行级 diff：相同上下文只渲染一次，改动行红绿底色并做行内字符高亮。它弥补内置 diffCardModel 对 PTC 与 str_replace_editor 不展示 diff、以及内置 DiffBlock 重复渲染上下文的问题；轮末提供「N 个文件已更改」汇总卡，支持审查、打开与右键在资源管理器中定位。安装命令为 dsh plugin add github:senyayume/dsh-edit-diff --profile desktop，host 半身需重启 harness 生效。
