Refactored scripts/ci_validate_repo.py to improve performance and memory efficiency. - Combined size check and NUL byte detection into a single pass. - Implemented early size check using stat() before reading file content. - Used chunked binary reading (64KB) for NUL byte detection to ensure constant memory usage. - Reduced system calls and improved script robustness.
