ci(release): explicitly add target std after toolchain setup

macos-13 (Intel) runner queue is too slow. Revert to macos-latest (arm64)
and add an explicit 'rustup target add' step to ensure x86_64-apple-darwin
std is installed for cross-compilation. dtolnay/rust-toolchain's targets
input occasionally doesn't install std in cross-arch macOS scenarios.
