- Detect Windows (.zip), Linux (.tar.gz), and macOS (.dmg / .app bundle) game archives during scan - Store GameFile[] with platform metadata in DB instead of plain zipFiles[] - Stream .app bundles as on-the-fly zip archives via archiver - Show WIN/LIN/MAC platform badge pills on GameCard and SeriesCard - Auto-select the download matching the user's OS in GameDetailModal - Persist cover URL to DB immediately on upload (no re-scan needed) - Backward-compatible: legacy zipFiles entries map to platform 'windows' Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
