justbustin/minecraft-crossover-bridge ? reverse-engineered prompt

Build me a cool proof of concept where I can play real Minecraft inside Monster Hunter World and Elden Ring on my Apple Silicon Mac using CrossOver.

I want Minecraft Java Edition to run natively, then somehow overlay itself into the game window so it feels like I am actually playing as Steve inside the other game. The Minecraft view should use the game camera, hide blocks behind the game world, and let me walk on the game’s real terrain. I also want monsters in the game to behave like Minecraft mobs, so I can hit them with swords and arrows and take damage back in Minecraft. Please make one key switch between normal game controls and Minecraft controls.

Set it up for both games, with separate install and run scripts, and make it easy to launch from the repo. If you need to look up current docs online for CrossOver, Fabric, or Apple Silicon setup, do that. Keep it safe so it only works for the supported game versions and does not guess if the game changes.
