DeepSeek Harness Universal Gateway Model Plugin

`dsh-gateway-provider` is a general-purpose LLM gateway provider plugin maintained by Luck9Star, designed to address the challenges of manually maintaining model lists and inaccurate parameters when using third-party gateways (such as NewAPI and LiteLLM) with DeepSeek Harness (DSH). This plugin allows users to mount a gateway directly as a provider route, supports automatic model list discovery, retrieves actual parameters (such as context window and output limits), and dispatches requests through native protocols. It provides a Web UI for configuration and supports independent routing and key management for multiple gateways. After installation, users only need to add and synchronize a gateway in the settings to conveniently use the models available behind the gateway.
