WASM Symbols Translator

Drop an uncompressed Emscripten symbols file and a Chrome profile trace JSON to translate wasm function names. For stack traces, paste text and translate it using the same symbols.

By default, this page reads cachebuster.txt and tries node_modules/@kognifai/cogsengine/dist/<cachebuster>/cogs.native.js.symbols.
