Webpack + WebAssembly the future

" summary

Claim: compiling Rust to WebAssembly yields a measurable speedup over equivalent JS. Demo uses cargo to target wasm, wasm-pack/wasm-bindgen and webpack to bundle, and instantiateStreaming to load modules. A factorial benchmark runs the function 5,000 times and WebAssembly completes in 224 ms while the JS version is much slower even after micro‑optimizations; JS tuning buys ~10–15% at best. Memory is shared via explicit buffers and bindings and the demo works end‑to‑end.
