Introducing the DeepSeek Harness Plugin: dsh-lanmode

`dsh-lanmode` is an enhanced LAN access plugin designed specifically for the DeepSeek Harness WebUI, aimed at addressing the limitations on non-local access under default security policies. By generating a Root CA certificate to support HTTPS, it unlocks browser security APIs such as microphone, clipboard, and file uploads. It also provides mDNS domain resolution (e.g., dsh.local), PWA support, quick access via QR code, and browser API polyfills. Installation requires DeepSeek Harness 0.1.7+ and Node.js 20+, making it suitable for developers who need voice interaction and remote access within a LAN.
