Fix validation issues identified in PR review

- Regenerate Package.swift to include new validation files
- Extract validation logic into reusable helper methods in DataSourceMetadata
- Add hash normalization to lowercase in RestoreImageRecord validation
- Add missing URL scheme validation with new error case
- Add assert for non-negative values in ReviewEngagementThreshold
- Update tests to cover new validation cases

Addresses all issues from PR #147 code review.
