The issue is that Homebrew libraries on macOS 14 runners are built for
macOS 14 and cannot be downgraded. We must use different deployment
targets based on the runner OS:
- macOS 13 runners: Can build for macOS 11.0 (HNSW) and 13.3 (DiskANN)
- macOS 14 runners: Must build for macOS 14.0 (due to system libraries)
This ensures delocate-wheel succeeds by matching the deployment target
with the actual minimum version required by bundled libraries.
