Destination path (for rename operations when file was deleted - file was moved to here). For renames: change_type="deleted", path = original path, moved_to = destination path. Empty string "" for non-rename operations (regular delete, add, modify).
NOTE: Rename tracking (moved_to/moved_from) is not currently supported. This would require additional tracking in the scanning system to detect and correlate MOVED events with source and destination paths. For now, renames are tracked as separate "deleted" and "added" events without the moved_to/moved_from fields. This is a future enhancement to keep the initial implementation simple.
