native host

This is a bit out of scope for this project, but I would like to host wasi + devices, natively, in [wamr](https://github.com/bytecodealliance/wasm-micro-runtime) or something.

This would mean all the demos that run here can run without a browser. [minifb](https://github.com/emoon/minifb) and [miniaudio](https://miniaud.io/) are nice, small & cross-platform, and would cover input/framebuffer/sound.

This could be the basis of [null0](https://github.com/notnullgames/null0), where you can make your game in anything, and run it on anything. The low-level devices would be available to mess with directly, but also higher-level helpers (like pntr) could be added to host for drawing, decoding, etc.

The issue mentions WAMR, minifb, and miniaudio but no repository files, tests, or entry point. First determine whether native WASI hosting belongs in this project and define a concrete integration boundary; done would require an agreed scope and a runnable non-browser demo.
