- electron/favorites.ts: persist favorites + recent (last 20) in userData
- electron/steam.ts: replace winreg callbacks with reg query execSync + fallback paths
- electron: new IPC handlers — favorites:get/toggle, recent:get; launch tracks recent
- UI: star button on cards (favorites), sort A→Z/Z→A toggle, skeleton loading,
  fade-in card animation, Epic/Favorites/Recent filter tabs, SVG placeholder with initials
