- Added windowed/fullscreen toggle: GameSettings.Windowed, saved in OptionsData, applied via Screen.fullScreenMode
- Settings menu row added, showing On/Off, toggles GameSettings.Windowed via left/right input
- Main menu Settings button opens same panel directly, before loading or starting new game
- ChosenAtMainMenu flag preserves main-menu setting choices through Continue and New Game
- Escape, Space, or F keys toggle windowed mode instantly from main menu screen
- Fixed scene wiring: settingsController and mainMenuManager references were unassigned, causing broken clicks
- Windows cursor hotfix: doubles cursor size specifically on Windows builds, unrelated but concurrent fix
