refactor: optimize runner error handling and cleanup logic

- Use defer for summary saving and HTML report generation to ensure they run regardless of exit path
- Remove unnecessary sync.Once for cleanup operations since defer guarantees single execution
- Simplify error handling logic by removing redundant runErr checks
- Improve interrupt handling with better logging messages
- Ensure graceful cleanup and data persistence even when interrupted
