- services/update_service.py: version compare + check_for_update (pure, tested)
- config: add update_source key (empty = no check)
- main_window: top banner, background-thread check; open folder via os.startfile
(QDesktopServices.openUrl mishandles file:// folder URLs — ShellExecute err 2)
- tests: +15 covering version compare and check_for_update branches
- docs 02/05/10 + tasks 17.16
