Function build_native_wasm 

pub fn build_native_wasm(
    rust_source: &str,
    crate_name: &str,
    work_dir: &Path,
) -> Result<PathBuf, String>

Build a function’s AOT module to a browser-loadable wasm32-unknown-unknown cdylib (HOTSWAP §Axis-3 / P17 — the browser analog of build_native_cdylib). The module is the same scalar-ABI shim; the wasm crate keeps logicaffeine-data + logicaffeine-system (both wasm-ready) but drops the desktop-only tokio, the logicaffeine-system full feature, and target-cpu=native. Returns the .wasm path; the browser then WebAssembly.instantiates it and the entry calls into it through the warm-bytecode indirection. Requires the wasm32-unknown-unknown target.
