ankitsinghsftc-droid/XACE ? reverse-engineered prompt

Build out XACE into a working schema driven gameplay platform.

I want a system where I can describe gameplay in a canonical game schema, validate it, compile it into a deterministic execution plan, and run it through a small authoritative runtime. The project should feel like the layer between a game idea and a game engine, not another game engine itself.

Please wire up the main flow end to end, from typed gameplay input to schema validation, compilation, runtime execution, snapshots, replay, and basic mutation handling. If there are already partial pieces in the repo, connect them instead of starting over. Keep the design engine independent, and make sure the runtime and compiler are the real source of truth.

Also make the developer experience solid, with clear examples, tests, and a simple way to run the builder locally. If you need to look up current docs for any dependency or runtime approach, go ahead and do that.
