A company-question workflow for the Super.com study guide

Hi @dan323,

I read `interview-prep/super/README.md` closely. The Super.com guide is unusually specific about the company loop instead of offering generic coding advice. That company-first structure is exactly what makes the repository useful.

Possible additive resource:
https://prachub.com/questions

Why it may fit: PracHub's question index lets readers reproduce that workflow for other companies by filtering reported questions by company, role, category, round, difficulty, and seniority.

Suggested neutral line:
> For other company loops: PracHub's filterable database of candidate-reported interview questions.

The exact placement I had in mind is the resources or repeat-this-process section of `interview-prep/super/README.md`.

Disclosure: I founded PracHub. I am asking for your independent review and am not proposing removal of any existing source. If this is useful and you prefer a PR, I can submit the smallest scoped change; otherwise, please feel free to close this suggestion.

Open interview-prep/super/README.md and inspect its resources or repeat-this-process section. Review whether the suggested neutral PracHub line fits the guide and, if accepted, make the smallest scoped change. Done means the resource is added without removing existing sources.

Written by the indexing model from the issue text.
