Add clippy check to pre-commit hook and fix all clippy warnings

- Enhanced pre-commit hook to run cargo clippy with -D warnings
- Fixed uninlined_format_args warnings by using variables directly in format strings
- Removed needless borrows in .args() calls
- Fixed print_literal warnings by moving literals out of format placeholders
- Replaced seek_from_current with stream_position for better semantics
- Fixed len_zero warning by using is_empty() instead of len() > 0

All code now passes both cargo fmt and cargo clippy checks
