Improves evaluation robustness and reporting

Enhances evaluation by improving error handling, providing more detailed logging, and adding a local summary calculation.

The changes include:

- Adds comprehensive judge fallback to Mind2Web judge and ensures backward compatibility.
- Improves error handling during evaluation by capturing and logging the last part of the output on failure.
- Adds a new function to calculate a summary of local evaluation results, displaying total tasks, success rate, and average score.
- Includes comprehensive evaluation data for debugging purposes.
