Windows: Antigravity shows generic icon in "Open in" menu instead of app icon

What version of the Codex App are you using (From "About Codex" dialog)?

26.325.3894.0

What subscription do you have?

Unknown

What platform is your computer?

Windows 11 x64

What issue are you seeing?

In the Windows desktop app, Antigravity appears in the "Open in" menu, but its icon is shown as a generic gray/default icon instead of the Antigravity app icon.

I verified locally that:

• Antigravity.exe itself has the correct app icon.
• Recreating the Windows Start Menu shortcut did not fix the icon shown in Codex.
• Codex's bundled apps/antigravity.png asset is correct.
• The issue therefore looks specific to Codex's Windows "Open in" icon resolution/runtime app list handling, similar to #16002 ("Wrong icon for Jetbrains IDEs").

What steps can reproduce the bug?

1. Install Antigravity on Windows.
2. Open Codex Desktop.
3. Open any workspace/thread with the "Open in" menu.
4. Open the "Open in" menu.
5. Antigravity is listed, but shown with a generic icon instead of the Antigravity icon.

What is the expected behavior?

Antigravity should display its actual app icon in the "Open in" menu.
