Simple Infinite Loop Detection

Not sure if this should be a Preflight check or an ESLint rule (opened upleveled/eslint-plugin-upleveled#36 and upleveled/eslint-plugin-upleveled#35 in the ESLint plugin too), but detecting infinite loops in student code would be really nice, especially when students get into using useEffect in React.

upleveled/eslint-plugin-upleveled#35 will help with warning about using useEffect without a dependency array, but there are other forms of infinite loops.

Some general ideas for infinite loop detection:
