dsh-voice-input-web: Adding Speech-to-Text Transcription to DeepSeek Harness Web Input Fields

dsh-voice-input-web is a client-side plugin for the DeepSeek Harness Web UI, designed to implement speech-to-text functionality through the browser's Web Speech API, requiring no API key or server-side modifications. The plugin adds a microphone button to the chat input toolbar; users can click it to start or stop listening, with real-time recognition results displayed in a floating overlay and the final text automatically appended to the input draft. It supports Chinese, English, and automatic language switching, with an optional auto-send feature. Installation methods include online and offline modes: for online installation, simply execute the `dsh plugin --profile web add dsh-voice-input-web` command and restart the service; for offline installation, manually place the package file and configure the patch file.
