apple/foundationdb ? reverse-engineered prompt

Build me a local version of FoundationDB from this repo and make it easy to run a small test cluster on my machine.

I want the project to compile cleanly, start the core server and client tools, and give me a simple way to verify that transactions work end to end with a tiny sample app or script. If there are missing setup steps, please add clear instructions or a small helper so I can get from fresh clone to working cluster without guessing. Also make sure the main command line tools are usable, and if there are tests that check the basic database flow, wire those up so I can run them easily.

If you need to check current build or dependency details online, do that. Keep the changes practical and focused on making FoundationDB straightforward to build, launch, and try out locally.
