Build me a browser mod for Agar.io that feels like a full featured upgrade to the game. I want it to work as a Tampermonkey style script, with automatic updates, and a polished in game overlay for chat, minimap, team info, and quick messages. It should include the useful gameplay helpers like extra zoom out, fast feed, double split, triple split, hotkeys, and a search tool for players, clans, and server info.

Please also make it support skins, themes, language packs, custom textures, and clan banners, with a settings screen where people can turn features on and off easily. The whole thing should feel fast, modern, and easy to use, with the ability to join party, FFA, team, and exp servers. If you need to check current browser extension docs or game changes online, go ahead and look them up.
