Add debug logging for coverage extraction

Adding debug output to:
- List all coverage files in both locations
- Show first 50 lines of coverage.xml
- Display extracted LINES and COVERED values
- Try alternative attribute names (elements/coveredelements)

This will help identify why coverage is showing 0%.
