Platform & Details
Computer: M4 Macbook Air

I also tried node 20 & 24, same error.

Please let me know what else I can provide.

Full error message
```Failed to check for exercise changes: Command failed with EBADF: git status --porcelain exercises/

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:

Comece reproduzindo a falha nas versões de macOS e Node informadas, concentrando-se no código que monitora alterações nos exercícios e executa `git status --porcelain exercises/`. Rastreie os erros `EMFILE` e `EBADF` e verifique se a verificação de alterações nos exercícios é concluída sem uma rejeição não tratada ou a saída do processo.
