fix: UX vereinfacht - doppelten Durchlauf entfernt + Paketliste im Prompt

- show_summary entfernt (war redundant nach collect_all_interactive)
- collect_all_interactive: keine log_step-Header mehr, nur einfaches
  'Additional Software (Obsidian, ...)? [Y/n]:' pro Modul
- module_description von optional/install listet jetzt alle verfügbaren
  Pakete, damit User die Liste sieht BEVOR er Yes/No sagt
- Nicht-required Module: kompakter confirm ohne log_step-Gedöns

install.sh
