xcxlang-org/xcx ? reverse-engineered prompt

Build me a small but real backend programming language project in Rust called XCX.

I want it to let someone write simple server code with built in HTTP, JSON, SQLite, crypto, and file I/O, instead of making them install a bunch of extra libraries. It should compile source into bytecode, run it in a virtual machine, and also have a tracing JIT so it feels fast. Support statically typed variables, fibers or coroutines, basic error handling, and the kind of syntax shown in the README for defining routes and database tables.

Please make it work on Windows, Linux, and macOS, and include a few example programs and tests that show a login endpoint and a tiny users API backed by SQLite. If something important is unclear, look up current docs online if needed and keep the implementation practical and clean.
