Subject: [PATCH] Fix extraction UI labels and speed for final extraction pass
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Force immediate emitState when first resolving archive items so UI
  transitions from 'Ausstehend' to 'Entpacken X%' instantly
- Use BELOW_NORMAL priority (instead of IDLE) for final extraction
  when all downloads are complete — matches manual extraction speed
- Add diagnostic logging for resolveArchiveItems matching
