/**
 * Antigravity Provider Configuration
 *
 * IMPORTANT: Model names MUST use `antigravity-` prefix for stability.
 *
 * The opencode-antigravity-auth plugin supports two naming conventions:
 * - `antigravity-gemini-3-pro-high` (RECOMMENDED, explicit Antigravity quota routing)
 * - `gemini-3-pro-high` (LEGACY, backward compatible but may break in future)
 *
 * Legacy names rely on Gemini CLI using `-preview` suffix for disambiguation.
 * If Google removes `-preview`, legacy names may route to wrong quota.
 *
 * @see https://github.com/NoeFabris/opencode-antigravity-auth#migration-guide-v127
