[ENHANCEMENT] Add batch processing statistics summary #3
Description
Description
When processing multiple files, it would be helpful to see a summary of statistics across all files.
Use Case

Proposed Solution
Add a summary section that shows:
- Total files processed
- Total lines removed across all files
- Average lines removed per file
- Processing time
