Fix extraction speed and UI label updates

Browse Source 
- Change OS priority from IDLE/BELOW_NORMAL to NORMAL/BELOW_NORMAL so
  extraction runs at full speed (matching manual 7-Zip/WinRAR performance)
- Use "high" priority in both hybrid and full extraction paths
- Increase hybrid extraction threads from hardcoded 2 to dynamic
  calculation (half CPU count, min 2, max 8)
- Fix emitState forced emit being silently dropped when a non-forced
  timer was already pending — forced emits now always replace pending
  timers to ensure immediate UI feedback during extraction transitions
