dsh-qq-onebot-bridge: A bidirectional bridge plugin between QQ and DSH agent

`dsh-qq-onebot-bridge` is a standalone plugin based on OneBot v11 reverse WebSocket, designed to implement a bidirectional bridge between QQ and the DeepSeek Harness (DSH) Agent. It drives QQ group and private chat messages directly into DSH sessions and automatically segments replies. Core functions include: 1. **Session Isolation and Memory**: Supports independent sessions for groups, individuals, or private chats; dialogue memory is persisted to disk and automatically re-injected after restarts; provides `/new` and `/status` commands for management. 2. **Multimedia Processing**: Supports private chat image recognition, group chat reference parsing (text/image/transcription), and Speech-to-Text (STT) and Text-to-Speech (TTS) based on Zhipu AI, OpenAI, or local GPT-SoVITS.
