Build 26351317

Changes

• Added the GnollHack controller layout for Steam Deck, which includes bindings for the back grips.
• Updated the back grip help text in Settings to explain the layout and the alternative F2, F3, F4, and F5 key bindings.
• Improved window close handling on Linux, so that a game in progress is saved when the window is closed or the system ends the game.
• Improved saving when the game is closed during a text prompt or a yes/no question.
• Starting GnollHack a second time on Linux now shows a message instead of opening a second copy of the game.
• Fixed a bug where save file tracking files could be treated as saved games on Steam Deck.
• Stopped sending a false error report to Sentry when closing the game on Linux systems that use IBus.
