phil0010-gh/openfront-helper — reverse-engineered prompt

Build me an unofficial Chrome and Edge browser extension for OpenFront that helps players find public lobbies faster and gives them optional helper overlays while they play.

I want a simple popup where users can turn features on and off, save their settings locally, and see a short what is new message after updates. The extension should work only on openfront.io and should not use analytics, tracking, accounts, or send user data anywhere.

The main features should include auto joining public lobbies, bot markers, nuke prediction, boat prediction, gold per minute stats, trade balance info, heatmaps, and alliance tools. Make the helpers feel lightweight and easy to understand, with clear labels and sensible defaults so a casual player can use it without reading a manual.

Please set it up as a normal browser extension with a manifest, background logic, content scripts, a built popup UI, translations if needed, and basic validation scripts. Look up current extension docs online if you need to.
