fix(cksum): correct CRC32B implementation to match GNU cksum

- Implement correct CRC32B algorithm with proper polynomial and initialization
- Add comprehensive test fixtures for CRC32B validation
- Support raw output format for CRC32B checksums
- Update dependencies and lock files for compatibility
- Fix code formatting and style issues
