fix: resolve build warnings and macOS checksum issue

- Fix sha256sum command on macOS by using shasum -a 256
- Prefix unused variables and fields with underscore
- Apply cargo fix for unused imports
- Add #[allow(dead_code)] for future-use code
- Clean up all compilation warnings

The build now compiles without any warnings, and the checksum
generation will work correctly on both Linux and macOS.
