Initial commit: JavaScript to WebAssembly compilation comparison

- 5 different JS-to-WASM implementations analyzed
- QuickJS (283KB) and Javy Static (519KB) are Wasmer-compatible
- Comprehensive size analysis and runtime compatibility testing
- Complete documentation and build automation
- Wasmer v6.1.0-rc.2 dynamic linking analysis included
