andrei1058/BedWars1058 ? reverse-engineered prompt

Build me a Minecraft BedWars plugin for Spigot and Paper that feels like a full featured arena minigame. Players should be able to join matches from commands, signs, NPCs, or a GUI, then defend their bed, buy items, upgrade their team, and eliminate other teams. Once a team bed is gone, those players should stop respawning and become spectators.

I want it to support multiple ways of running the game, like a shared server setup, a full multi arena setup, and a proxy based setup for bigger networks. Make the lobby, shop, upgrades, stats, parties, and messages configurable, and let different languages be used per player. It should also handle map restore after each game, with a faster option if a world manager plugin is available.

Please make it work on modern Minecraft versions, keep the code clean and organized, and look up current docs online if you need to.
