fix: Resolve macOS build breakage and restore tools audio support

Updates gpu.cc to handle modern wgpu-native callback signatures (5 args) for macOS while maintaining Windows compatibility. Modifies audio.cc and CMakeLists.txt to ensure miniaudio encoding features are only stripped from the demo binary, not the tools (spectool/tests).
