Implement library rules validation and zip extraction utility

- Added `is_library_allowed` function to evaluate library permissions based on defined rules.
- Introduced `rule_matches` helper function to check OS compatibility for rules.
- Created `extract_zip` function to handle zip file extraction, including directory creation and skipping of META-INF entries.
