Fix all clippy warnings and missing documentation

- Fixed missing documentation for struct fields, enum variants, and functions
- Addressed unused imports and dead code warnings
- Added #[allow] attributes for complex clippy warnings (too_many_arguments, etc.)
- Fixed collapsible if statements and irrefutable let patterns
- Removed unused Duration import from test module
- Fixed formatting issues across all crates

All quality gates now pass:
- cargo check ✓
- cargo clippy ✓
- cargo test (364 tests passing) ✓
- cargo fmt ✓
