Subject: [PATCH] fix: skip i686 builds and add EPEL for Linux wheel builds

- Add *_i686 to CIBW_SKIP to avoid 32-bit Linux builds that lack
  compatible scipy/OpenBLAS packages in manylinux containers
- Install epel-release before eigen3/openblas on CentOS-based images
- Add || true fallbacks so missing packages don't fail the entire build
