dsh-classroom-mobile: Mobile browser recording + Local transcription + Post-class organization DSH workflow plugin

The DeepSeek Harness plugin dsh-classroom-mobile, maintained by chengyu-xin1, is categorized as a workflow. It integrates mobile browser recording, local faster-whisper transcription, Agent-generated summaries and Mermaid mind maps, practice problem grading and error gating, and focus event recording into a cohesive post-class learning chain. The mobile device accesses the PC-side service via a temporary cloudflared HTTPS tunnel and also supports LAN HTTP within the same Wi-Fi network. The plugin has zero npm dependencies and uses only Node.js built-in modules. All data is written locally to D:\dsh-classroom-mobile\data and is not uploaded to the cloud.
