clean: remove debug output from ZIP structure fix

Removed all temporary debugging output added during the ZIP structure
investigation. The fix has been verified to work correctly:

- XLSX files now have proper internal structure when unzipped
- No unwanted directory layers (like random hex strings) appear
- All working directory strategies (.alongsideOutput, .systemTemp, .custom) work correctly
- All existing tests continue to pass

The core fix (URL symlink resolution in SimpleZip.collectEntries) remains intact.
