Subject: [PATCH 1/2] Fix integration test failures and improve cross-platform
 compatibility

- Updated .gitignore to properly exclude temporary and cache files that were causing test environment issues
- Enhanced automation_core.py with cross-platform command handling for Windows, macOS, and Linux systems
- Added safety checks for system commands and improved error handling in automation engine
- Modified integration tests to properly import memory_manager module and fix path resolution
- Updated benchmark suite to handle missing numpy dependency gracefully and prevent timeouts
- Improved concurrent command handling and thread safety in automation core module
