🐛 fix: fix: category, Chrome session, GNOME app-folder integration

- Manager .desktop: Categories=GTK;Utility → Categories=GTK;Webapps
- big-webapps-exec: Default/Browser profile → native Chrome
  --profile-directory=Default (keeps user logins/cookies);
  custom profiles → isolated --user-data-dir
- desktop.rs: ensure trailing semicolon in Categories= field
- desktop.rs: reset GNOME app-picker-layout on desktop file change
  (GNOME Shell caches app positions, preventing category changes
  from moving apps to correct folder)
