Patch v0.8.89

This update improves window handling, tablet tabs, and UI scaling. [*] Tablet tab fixes: Fixed the tab picker appearing behind websites and restored access to closed tabs. Reopen-menu icons now match their tabs. [*] Alt+Tab improvements: Updated window handling to address duplicate game entries and lingering entries after closing. [*] Borderless fullscreen: Replaced windowed mode with borderless fullscreen for more consistent framing across monitor sizes and Windows scaling settings. [*] UI scaling fixes: Packs, opening instructions, control hints, Card Care, and Collect Cards now follow the scaled game area. Fixed Card Care positioning after resizing. [*] Smoother menu startup: The main menu now waits for its background and logo to load, then fades the artwork and controls in together.
