DeepSeek Harness Subscription Integration Plugin

The DeepSeek Harness (DSH) plugin `@h2mzzz/dsh-openai-subscription` enables developers to invoke models using ChatGPT/Codex subscription accounts without configuring an API key. It provides a dynamic model list, thinking intensity adjustment, quick mode, image generation, and quota query features. After installation, users can log in and refresh models on the DSH settings page, then select a subscription model in a conversation. The plugin supports independent login management, a compact model panel, and sliders for adjusting parameters, aiming to simplify the use of ChatGPT subscription models. However, some features (such as image generation and quota queries) are experimental and rely on unstable APIs.
