opensnap/antigravity ? reverse-engineered prompt

Build me a simple Linux installer for Google Antigravity 2.0 that works on Ubuntu and Debian with one command.

I want it to download the latest official Google tarball at install time, set everything up system wide, and add desktop launchers, icons, and command line shortcuts so I can open Antigravity normally from the app menu or terminal. It should also support installing the Antigravity IDE too, with an option to install both together or just one of them.

Please include easy update, status, and uninstall commands, and make sure updates can reuse the stored install URL when available. If possible, add file manager integration so folders can be opened in the IDE from right click or Open With. Keep the sandbox behavior safe by default, and do not disable it just to make things easier.

If you need to check current download details or docs online, go ahead. I also want the script to be clean, well commented, and safe enough that someone can inspect it before running it with sudo.
