Pull Request Overview

This PR adds console logging for ERROR level messages in the task agent. Previously, log messages were only written to a file handler; now ERROR and above severity messages will also be displayed on the console for immediate visibility.

Key Changes

• Added a StreamHandler to output ERROR level and above messages to the console
• Configured the console handler with a simpler format than the file handler
