fix(ci): Disable musl targets that exceed 6-hour timeout

Cross-compilation for musl targets (x86_64-unknown-linux-musl and
aarch64-unknown-linux-musl) takes over 6 hours due to needing to
compile LLVM/clang from scratch in the cross Docker container.

This disables musl targets for now. To re-enable, we need:
- Pre-built Docker images with clang-14 already installed
- Or use cross's custom Dockerfile feature

All other targets now build successfully:
- Linux glibc (x86_64, aarch64)
- macOS (x86_64, aarch64)
- Windows (x86_64, aarch64)
- Docker image
