Hi @murshed Thanks for taking the time to contribute to WordPress Studio! 🙏

I have a few questions and suggestions to help get this PR ready:

1. Verify the bundle ID

I noticed the macOS bundle ID is com.google.Aantigravity (with double-A). I've ran a test in my machine and it seems it should be com.google.antigravity. Could you confirm this is correct?

2. Split into separate PRs

This PR mixes two different types of changes. Would you mind splitting this into:

• One PR for the editor addition (with testing details)
• One PR for documentation improvements (if still desired)

This makes it easier to review and provides better git history.

3. Formatting changes

The test file has many whitespace-only changes, which will fail our npm run lint check. Could you please fix the issues?

4. Complete the PR template

Could you fill out the "Proposed Changes" and "Testing Instructions" sections? This helps reviewers understand:

• Why this change is valuable
• How to verify it works correctly

Thanks again for your interest in improving Studio! Let me know if you have questions.
