Skip sources that already have imported games and avoid importing
platforms that are disabled in settings.
Remove imported games when a source is disabled so the library stays in
sync with user preferences.
Ensure persistence operates on the full game list, not filtered rows.
Deduplicate imported entries by stable game ID to prevent missing games
and regressions when importing from multiple sources.
Initial release of A-La-Karte, a unified game launcher for KDE Plasma.
Includes the QML UI, platform importers, AppStream metadata, icons,
and developer documentation.
