Increase timeout for page load stability in Chrome evaluator - Updated the timeout for the page load state from 10 seconds to 60 seconds to ensure better stability during page processing. - Removed redundant retry mechanisms from the active tab checks to streamline the code while maintaining existing functionality. - Enhanced logging to provide clearer insights into the page loading process. These changes aim to improve the reliability of the Chrome evaluator without altering the core logic.
