Subject: [PATCH] Make Arch.hostArchitecture() fail fast on unsupported
 architectures.

The compile-time #if/#elseif switch in hostArchitecture() covered only
arch(arm64) and arch(x86_64) with no #else, so on any other architecture
the function had no return statement and produced a confusing missing-return
error. Add an #else that emits a clear #error diagnostic, mirroring the
explicit unknown-architecture handling in ClientKernel.swift. This is
behavior-preserving on the two supported architectures.
