dsh-gemini-oauth-bridge: Integrating Google AI Subscription with DeepSeek Harness

`dsh-gemini-oauth-bridge` is a plugin designed to enable DeepSeek Harness (DSH) to directly use Google's subscription quota. It converts Google's OAuth flow into an OpenAI-compatible interface, supporting streaming and non-streaming conversations, multimodal images, function calling, and automatic token refresh. Users can complete setup with a one-click login and access it via the local port 3080. The plugin relies on non-public APIs, poses risks associated with non-official accounts, and supports only a single account and data-URL image format.
