Some small tips

[ghost]

1. Specifying exceptions:goto is optional with gc:arc since arc/orc already imply them. It might be useful to be more explicit though, so that's up to your own discretion :)

2. To solve the Calling stub instead of signal() you'd usually want to use -d:noSignalHandler so Nim doesn't generate its own signal handlers

3. I feel like it's better to not commit the .exe files (or .wasm .data .html) to the repo
