dsh-streaming-mcp-bridge: DSH Real-Time Streaming Bridge Plugin

`dsh-streaming-mcp-bridge` is a community plugin for DeepSeek Harness (DSH), designed to address the limitation that the ACP protocol returns only the final result and does not allow real-time observation of the thinking process. By bridging Harness's `session.event` and `session.status` streams, it supports Streamable HTTP MCP and ACP Adapter for Feishu, enabling real-time task progress updates. The plugin must be installed as a Bundle, supports Bearer Token authentication, and should listen only on a local address for security.
