Code Review

This pull request refactors the third-party dependency initialization logic, making it more robust by checking whether initialization is necessary before running it. The changes are mostly in utils.py, with corresponding adjustments in setup.py. The new logic checks submodule status, patch application status, and the presence of required libraries. While the overall logic is a good improvement, there are some critical issues in the implementation where utility functions terminate the program using exit(1) instead of propagating errors to their callers. This makes the code less predictable, reusable, and testable. I've left comments with suggestions to fix these issues by replacing exit(1) with more appropriate error handling mechanisms.
