Implements bit-perfect audio playback for USB DACs on Android 14+ devices, addressing issue #157. This feature allows audio to be sent directly to external USB DACs without resampling, mixing, or processing by Android's audio system, preserving maximum audio quality for high-resolution files. Changes: - Add BitPerfectManager to detect USB DAC connections and configure bit-perfect mode using AudioMixerAttributes API - Add MODIFY_AUDIO_SETTINGS permission required for audio configuration - Add user preference toggle in Playback settings - Integrate with existing playback architecture via dependency injection - Automatically activates when USB DAC is connected and preference is enabled - Requires Android 14 (API 34) or higher The implementation monitors USB device attach/detach events and queries supported mixer attributes to configure the optimal bit-perfect playback mode for connected DACs.
