Enhance debugging: Improve logging for FURIOSA_METADATA_EXPECT_MODIFIED patterns

[hyeokjunejeon]

This PR enhances the debugging information related to the FURIOSA_METADATA_EXPECT_MODIFIED setting. It provides clearer insights into whether a file is considered 'dirty' or 'pass' based on the configured patterns.

Key changes:

• Add more detailed logging for files matching or not matching the FURIOSA_METADATA_EXPECT_MODIFIED patterns
• Clarify which patterns are working as expected and which are not

Motivation:
Previously, we had to rely on guesswork to determine if the patterns were functioning correctly. This lack of clear information made it difficult to debug and verify the behavior of the FURIOSA_METADATA_EXPECT_MODIFIED setting.

With these changes, we can:

1. Easily identify which files are being flagged as 'dirty' or 'pass'
2. Quickly verify if the configured patterns are working as intended
3. Reduce the time spent on debugging pattern-related issues

This improvement will significantly enhance our ability to manage and debug metadata-related configurations, leading to more efficient development and troubleshooting processes.
