Elytrium/LimboAuth ? reverse-engineered prompt

Build me a Minecraft authentication plugin for a Velocity proxy that works through a virtual limbo server, so players can be sent into a safe login area until they register or sign in.

I want it to support H2, MySQL, and PostgreSQL, plus Floodgate and Geyser users, with hybrid online, offline, and Floodgate mode support. Please include password hashing with BCrypt, weak password blocking, session handling, two factor auth with TOTP, and commands for things like register, login, logout session reset, change password, premium or license mode, and admin force register or force login actions.

Make the messages and settings easy to customize, and let the plugin load a simple schematic world for the limbo area. If there’s anything unclear from the current docs, look up the latest info online and follow the existing project style.
