Breaking
There are now server and client features that must be enabled properly.
The old behavior was to simply separate code by target arch. However, this prevented you from compiling the server
side logic as WASM, which you might want to do in certain cases.
Server-Side WASM
The output directory has changed to prebuilt/, because you will now also find prebuilt server side WASM that
can't only solve a challenge, but also create a new one and validate. This makes it possible to host the server
side not only from a Rust backend, but basically anything that can work with WASM in the backend like NodeJS.
