fix: menu options now actually execute instead of silently exiting

The update and reinstall cases in the menu were missing exit statements,
causing the script to continue running after completion and hit the fresh
install path. This made it appear as if nothing happened when selecting
menu options.

Added exit 0 after print_completion for both update and reinstall cases.
Removed debug output now that the issue is resolved.
