Rust target installation will fail for universal-apple-darwin.
universal-apple-darwin is not a valid Rust target triple. The dtolnay/rust-toolchain action at line 39 will either fail or have no effect. The build script actually needs both x86_64-apple-darwin and aarch64-apple-darwin targets installed to compile the universal binary.
🐛 Proposed fix: Install both actual targets for universal builds

Workflow target configuration needs fixing for universal binary builds.
The packaging logic using lipo is correct. However, the libmoq.yml workflow incorrectly tries to install universal-apple-darwin as a Rust target (line 34), which doesn't exist. For the universal build job to succeed on macos-latest (ARM runner), the workflow should instead install both x86_64-apple-darwin and aarch64-apple-darwin targets before running build.sh. The build script itself correctly handles the "universal-apple-darwin" target by explicitly building both architectures and combining them with lipo, but this requires both underlying targets to be available.

In order to build the moqbs fork properly for macos, we need a unified build for macos that support both architectures.
