- Disable old unified-build.yml workflow (was causing conflicts)
- Create new unified-release.yml with proper platform separation
- macOS builds now run on macOS runners (fixes cross-compilation)
- Linux and Windows builds use Ubuntu with cross-compilation
- Separate build jobs for each platform to prevent cancellation
- Rename workflow to indicate cross-platform support
Platform matrix:
✅ Linux x64: Ubuntu runner (native)
✅ Windows x64: Ubuntu runner (cross-compile)
✅ macOS x64/ARM64: macOS runners (native)
✅ Android: Ubuntu runner (native)
✅ Backend: Ubuntu runner (native)
