Made a companion app to track RetroAchievements and guides while playing

Version 0.4.0-beta of game-twin introduces integration with RetroAchievements, allowing users to track achievements by entering their username and API key in the settings. It supports automatic game linking through recently played detection, manual entry, or RetroAchievements game ID, and features an Achievement Grid View with logos for progress tracking. The update also includes last played game detection that works alongside RetroArch and ES-DE, enabling functionality on any Android device without needing Wi-Fi sync. Additionally, a Table of Contents feature improves navigation for compatible web pages both online and offline.
