[FEATURE] Rosetta Code AI experiments

[podhrmic]

Summary

If #135 turns out to work OK, use Rosetta Code examples from #136 as a test harness for CN.

The goal is to:

1. find the examples that lead to actual warnings about UB
2. create another agent that fixes compiler warnings (such that we want the code to compile without warnings before we start applying CN) (maybe the front LLM is fine to generate fixes, but we will need a GCC/clang agent that compiles the code)
3. once we have code that compiles without warnings, pass it to the CN agent for UB fixes
4. see if specs can be generated and if they make sense
5. document your progress
