The monolithic settings schema has been refactored into a modular feature gate system. Features like autoMode, deepLink, voice, assistant, and briefView are now individually defined with their own buildGate(), shape(), and permissionsShape() methods, making the settings system more maintainable and enabling conditional feature compilation.
