[Feature Request] Official Support for Google Antigravity IDE

Feature Request: Support for Google Antigravity IDE

Description
Google recently released Antigravity, a new AI-first IDE based on VS Code. Many developers are migrating to this editor, but the official PlatformIO IDE extension currently does not function correctly out of the box.

Current Behavior
When installing the PlatformIO extension in Antigravity:

1. The extension installs but fails to activate.
2. It conflicts with the internal Python environment (Antigravity ships with Python 3.14, which seems to cause stability issues with the current PIO Core bootstrapping).
3. The Extension ID is not recognized correctly by the PIO home process, preventing the sidebar from loading.

Known Workarounds (Community)
Users on the PlatformIO community forums have found temporary fixes by:

• Manually patching extension.js to update the Extension ID.
• Forcing the internal penv to use a compatible Python version (e.g., 3.11) instead of the IDE's bundled Python 3.14.

Request
Please add official support for the Google Antigravity environment. This likely involves:

• Whitelisting the Antigravity engine/product ID.
• Ensuring the Python discovery script handles the Antigravity PATH correctly.

Environment

• OS: [e.g., Windows 11 / macOS Sequoia]
• IDE: Google Antigravity (latest release)
• VS Code Core Version: [Check Help > About]

It would be great if official support for Antigravity IDE could be added, especially handling its internal Python environment and whitelisting the IDE engine/product ID.

I've submitted 2 fixes for this:

#4463
platformio/platformio-node-helpers#24

It works when I build with these changes. Not specific to AG - should work with any forked version of vscode IDE.
