🤖 Fix: Use shell parallelism for macOS builds

Changed from Make dependency parallelism to explicit shell parallelism:
- dist-mac now runs both architectures with '&' and 'wait'
- This ensures true parallel execution (not sequential)
- dist-mac-x64/arm64 still available for individual builds

Previous approach didn't work because Make doesn't parallelize prerequisites
that all depend on 'build' - it ran them sequentially to be safe.
