dsh-router: OpenAI-Compatible Routing Plugin for DeepSeek Harness

dsh-router is a plugin for DeepSeek Harness (DSH) designed to provide a native OpenAI-compatible API. It addresses the maintenance challenges of traditional gateways that manage multiple services, enabling unified provider and policy management through pluggable integration. It supports account pool scheduling, composite fallback, and Team-scenario isolation. Users can configure providers, fallback chains, and models in the settings panel, with data automatically synchronized to the DSH model list and usage dashboards provided. This plugin requires DSH version 0.2.0 or later.
