Simplify to Apple Silicon only (drop Intel support)

Remove Intel/x86_64 build complexity:
- Build only for arm64 (Apple Silicon)
- Remove universal binary creation steps
- Remove architecture detection and lipo complexity
- Simplify workflow significantly

SwiftMac now targets modern Macs:
- M1, M2, M3, M4, and future Apple Silicon

Updated documentation to reflect Apple Silicon requirement.
