Description

• Added the new NzbDirArchiveScan option to toggle the feature, and NzbDirArchiveAction option to decide if the original archive should be deleted or moved to a _processed folder when done.
• Sandbox Extraction: Archives are extracted to a temporary _unpack directory. Valid .nzb files are filtered and moved to the active directory for queuing.
• Data Loss Prevention: If an archive contains files other than .nzb, the system refuses to delete it (even if set to delete) and instead moves it to the _processed folder. Failed extractions are moved to _broken.
• Robust File Operations: Added cross-device file move utilities and collision-free unique file naming (e.g., archive(1).zip);
• Refactored logic to more stable error-handling approach and added extra logging
