Copy MHBridge into the Erupe module as cmd/protbot/ so it can be built, tested, and maintained alongside the server. The bot implements the full sign → entrance → channel login flow and supports lobby entry, chat, session setup, and quest enumeration. The conn/ package keeps its own Blowfish crypto primitives to avoid importing erupe-ce/config (which requires a config file at init).
