Google Antigravity Plugin

The Google Antigravity plugin connects Eliza agents to Google Cloud AI Platform, providing access to Google's cloud-hosted AI models through the Google Cloud API. This is the Google Cloud (Vertex AI) integration, as opposed to the Google Gemini plugin which uses Google AI Studio.
