Enhance Chrome evaluator with improved error handling and retry mechanisms

- Added robust error handling for page processing, including checks for closed pages and HTTP status codes.
- Implemented retry logic for page loads and active tab checks to improve reliability.
- Enhanced logging throughout the process to capture detailed information about failures and successes.
- Preserved existing logic while ensuring better maintainability and robustness in the Chrome evaluator functions.
