Hi @rmondello, thanks for reviewing!

Sorry for the unclear commit message. This PR actually adds two entries sharing the same Apple Developer Team ID (2DE8QTFYGR):

Tabbit Browser (com.tab-browser.Tabbit) — the domestic version for users in China. Website: https://www.tabbit-ai.com/
Tabbit (com.tabbit-ai.Tabbit) — the international version for users outside China. Website: https://www.tabbitbrowser.com/
Both are Chromium-based browsers for macOS built from the same codebase. They are released as separate apps targeting different markets, with differences in AI model integration, default language, branding, and some other features.

Please let me know if you need any additional information. Thank you!
