feat: LAN update check on startup with notify banner (stage 2)
Read manifest.json from the configured update_source and show a dismissable banner when a newer version is available. Notify-only — no install yet. - 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 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
