dsh-conversation-exporter: Export DeepSeek Harness Conversations to Markdown

dsh-conversation-exporter is a local plugin maintained by liuyuelintop that exports DeepSeek Harness (DSH) Web interface conversations into clean Markdown files, addressing the poor readability of native Session Logs. It supports full exports and round-based filtered exports, with all processing performed locally, no cloud uploads, and preserved rich text formatting. Users can install it via terminal commands and download exported files by clicking the “Export Chat” button in DSH Web. The generated Markdown files include conversation titles and message quote blocks, but exclude debugging information. The plugin is currently compatible with DSH version 0.1.0-rc.6.
