Add LAPACKE/LAPACK packages to all platform installation instructions

Updated installation commands for all supported platforms to include LAPACK:
- Arch Linux: added lapack package
- Fedora: added lapack-devel package
- OpenSUSE: added lapack-devel package
- CentOS/Rocky/AlmaLinux: added lapack-devel package
- macOS (Homebrew): added lapack package
- macOS (MacPorts): added lapack package
- FreeBSD: already includes lapack in BLAS (no change needed)

All platforms now have proper LAPACK support documented.
