Summary of Changes

Hello @dlarocque, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request reverts the previously introduced emulator overlay functionality. It systematically removes the updateEmulatorBanner function and its related UI components, which were designed to display a visual banner when Firebase SDKs were connected to an emulator, particularly in cloud workstation environments. This change cleans up the codebase by eliminating unused imports and function calls across multiple Firebase packages, effectively undoing the visual indicator for emulator connections.

Highlights

• Removed Emulator Banner Logic: The updateEmulatorBanner function and all its associated UI logic for displaying an emulator overlay banner have been completely removed from the @firebase/util package.
• Cleaned Up SDK Integrations: Imports and calls to the updateEmulatorBanner function were removed from the Auth, Database, Firestore, Functions, and Storage SDK packages, streamlining their emulator connection logic.
• Simplified Ping Server Calls: In Functions and Storage SDKs, the pingServer calls were simplified by removing specific path suffixes (/backends and /b), as the updateEmulatorBanner function which used these paths is no longer present.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request reverts the 'Emulator Overlay' feature. The changes consistently remove the updateEmulatorBanner function, its implementation in @firebase/util, and its usage across the auth, database, firestore, functions, and storage packages. The API review file is also updated accordingly. The modifications to pingServer calls in the functions and storage packages also appear to be part of this revert, restoring previous endpoint paths. The changes are clean and focused on the revert, and I see no issues.
