fix: resolve CI conflicts and Python finding issues

- Remove duplicate ci-cibuildwheel.yml workflow to avoid confusion
- Fix DiskANN CMakeLists.txt to support both standard and manylinux builds
- Try Development.Module first (manylinux), fallback to Development (standard)
- Keep build-reusable.yml and build-cibuildwheel.yml as separate workflows
- They build different wheel types and are selected at release time
