Added the required JNI constructor `(IntPtr, JniHandleOwnership)` to `OsuGameActivity` to prevent `System.NotSupportedException` during startup on Release builds with aggressive trimming. This constructor ensures that the managed counterpart of the activity can be correctly activated by the .NET Android runtime when the Java-side instance is created. All initialization logic (creating `OsuGameAndroid` and input handlers) has been moved/duplicated into this constructor to ensure the game state is valid immediately upon activation.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |
- Added the required JNI constructor `(IntPtr, JniHandleOwnership)` to `OsuGameActivity` to prevent `System.NotSupportedException` during startup on trimmed builds. The constructor calls the parameterless base and ensures proper game initialization. - Robustified Daily Challenge logic by replacing `Playlist.Single()` with safer alternatives to prevent "Sequence contains no elements" crashes when the playlist is empty or being populated. - Fixed a crash in `TestSceneDailyChallengeIntro` caused by force-unwrapping a null `RoomID`. - Improved stability of visual tests (`TestScenePlaylistsRoomCreation`, `TestScenePlaylistsRoomSubScreen`, `TestSceneDeleteLocalScore`) by using `AddUntilStep` and adding defensive checks for asynchronous state updates.

Specifically resolved CS1643 by ensuring all lambda paths return a value and flattened nested `AddUntilStep` calls.
