AG X (Antigravity fork) v2.0.3

AI-Powered Code Intelligence — agentic desktop application with multi-provider AI support.

What's New in v2.0.3

🐛 Critical Fix: Provider Selection Flow

• Welcome screen now shows BEFORE the Language Server starts — on first run, the user picks a provider before the LS launches, preventing the Google OAuth prompt from appearing for non-Google providers.
• Provider config syncs to ~/.codex/endpoints.json — the provider choice from the welcome screen and settings panel is properly synced to the endpoints config that the translation proxy reads.
• "Another AI Provider" flow fixed — when user picks a custom provider, the settings panel opens and the app waits for the user to configure and save their provider before starting the Language Server.

Changes
