/**
 * Google Antigravity Auth Plugin for OpenCode
 *
 * Provides OAuth authentication for Google models via Antigravity API.
 * This plugin integrates with OpenCode's auth system to enable:
 * - OAuth 2.0 with PKCE flow for Google authentication
 * - Automatic token refresh
 * - Request/response transformation for Antigravity API
 *
 * @example
 * ```json
 * // opencode.json
 * {
 *   "plugin": ["oh-my-opencode"],
 *   "provider": {
 *     "google": {
 *       "options": {
 *         "clientId": "custom-client-id",
 *         "clientSecret": "custom-client-secret"
 *       }
 *     }
 *   }
 * }
 * ```
