Fixed random overlay flips during scrolling and clicking through the game grid.
- Replaced visual-tree scan/cache heuristics with event-driven DataContext hooking so tile overlays update synchronously with Playnite's own container virtualization/recycling
- Compatibility database entries now keyed by the game's stable Playnite GUID, preventing conflicting stored values for the same game
- Restored controller icon glyph in tile overlay badges
