Subject: [PATCH] fix(program): add defensive `null` checks and fix syntax
 error

- [x] add `null` check for `self.requires` in `requirements()`;
- [x] fix a malformed format string in `ollama_client.cpp` debug mode;
- [x] add `null` checks in `CurlUtils::cleanup()` method;
- [x] add debug logging for `curl` pointers during cleanup;
