sondernextdoor/engine-ve ? reverse-engineered prompt

Build me a chess engine project that can play a full game of chess from the command line and be easy to test and improve. I want the core engine in C++ and I want it organized so I can run basic tests, verify move generation and rules, and have a place for training or tuning work later if needed.

Please make sure it can load a position, generate legal moves, pick a move, and print the result in a simple way. If there are any missing details in the current setup, use sensible defaults and look up current docs online if you need to. I also want the project to be clean enough that I can build it locally and run the tests without a lot of setup. If it makes sense, include a simple evaluation so the engine does something reasonable instead of just random moves.
