Subject: [PATCH] fix: ensure wheels are compatible with older macOS versions

- Set MACOSX_DEPLOYMENT_TARGET=11.0 for HNSW backend (broad compatibility)
- Set MACOSX_DEPLOYMENT_TARGET=13.0 for DiskANN backend (required for LAPACK)
- Add --require-target-macos-version to delocate-wheel commands
- This fixes CI failures on macos-13 runners while maintaining M4 Mac support

Fixes the issue where wheels built on macos-14 runners were incorrectly
tagged as macosx_14_0, preventing installation on macos-13 runners.
