fix: improve symlink handling in cut operation

Modify symlink handling in DoCutFilesWorker to defer deletion until after
successful link creation:

- Replace immediate deletion with deferred deletion via cutAndDeleteFiles list
- Only add symlink to deletion list if creation was successful
- Maintain existing completion tracking behavior

This change prevents premature deletion of symlinks and ensures atomic
cut operations for symbolic links.
