Flashback Turbo

Silent auto-update. FlashbackTurbo now keeps your Zeffut mods up to date automatically: on launch it checks Modrinth for newer versions of the mods in your mods/ folder (matching your loader + MC version), downloads verified updates in the background, and swaps them in when you quit the game (a detached helper finishes the swap on Windows). Opt out with "autoUpdate": false in config/flashbackturbo.json (or -Dautoupdate.enabled=false).
