Highlights:
• Added Vulkan and OpenGL renderer selection in Video options; changes apply after a restart.
• Added separate UI Volume and Spatial Audio controls.

Added:
• World-positioned card, hand, shop, and deck sounds with adjustable stereo strength.
• Renderer-aware shader support for Vulkan and OpenGL.

Changed:
• Music transitions now wait for the next musical bar for smoother scene changes.
• Audio recovery and volume clamping are safer after focus or device changes.

Fixed:
• Recovered audio voices restart correctly instead of leaving music silent.
• New audio and renderer labels are localized across supported languages.
