feat: complete ScanConfig with all core scanning fields

- Add sbomgen_version, timeout, platform, scanners, skip_scanners, skip_files fields
- Implement parse_comma_list() helper for robust comma-separated string parsing
- Add string-to-int conversion for timeout field
- Add comprehensive test coverage for all new fields and helper function
- ScanConfig now provides complete replacement for scanning-related args

Features:
- Type-safe field access with proper data conversion
- Robust comma parsing with whitespace handling and empty string validation
- 35 comprehensive tests ensuring reliability
- Clean, readable code without syntactic sugar
- Foundation ready for replacing args object usage in orchestrator

This completes the core scanning configuration data model, enabling
the next phase of strangler fig migration to extract services.
