Fix extraction progress caching and JVM tuning

- Replace Map-based archive item cache with plain Object.create(null)
  to work around mysterious Map.has() returning false despite set()
  being called with the same key — this caused resolveArchiveItems
  to run on every 1.1s pulse instead of being cached, preventing
  extraction progress (Entpacken X%) from ever showing in the UI
- Apply same fix to both hybrid and full extraction paths
- Increase JVM heap from 512MB to 1GB for better extraction throughput
- Use SerialGC for faster JVM startup on short-lived extract processes
- Add download lifecycle logging (package add + item download start)
