Antigravity VS Code Chat Provider

This extension registers a LanguageModelChatProvider for Antigravity so the models show up in Copilot Chat.

Usage

1. Run Antigravity: Sign In from the Command Palette.
2. Open Copilot Chat and select an Antigravity model from the model picker.

The extension stores tokens in VS Code SecretStorage and refreshes them automatically.

Notes

• OAuth uses http://localhost:51121/oauth-callback for the local redirect.
• Antigravity models use the antigravity- prefix for quota routing.
• Gemini CLI models use the -preview suffix.
