fix(cli): migrate Gemini models to explicit antigravity- prefix for quota routing

Browse Source 
All Gemini model references now use the `antigravity-` prefix to ensure explicit
routing to Antigravity quota pools instead of relying on legacy `-preview` suffix
disambiguation. This approach prevents potential breakage if Google removes the
`-preview` suffix in future versions.

Updates include:
- config-manager: Updated Gemini model assignments with antigravity- prefix
- config-manager.test.ts: Updated test assertions to match new naming convention
- install.ts: Updated config summary display to show antigravity-prefixed model name

Migration follows opencode-antigravity-auth plugin v1.2.7+ guidance for explicit
quota routing configuration.

/**
* 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
