fix: Add MinGW build support and compatibility fixes

- Add MinGW compatibility shim for cpp-httplib GetAddrInfoExCancel
- Fix portaudio linking (portaudio_static -> portaudio)
- Disable -Werror for MinGW builds due to httplib incompatibilities
- Add console subsystem flag for MinGW builds
- Add debug logging utilities (Logger.h)
- Add MessageBox debugging for Windows troubleshooting
- Update build scripts with better error handling
