* fix(ds4): add Homebrew include/lib prefix for Darwin grpc-proto build

The darwin/metal ds4 backend job runs for the first time on this bump
(it was skipped on prior ds4 PRs) and fails compiling backend.pb.cc with
'google/protobuf/runtime_version.h' file not found.

hw_grpc_proto links neither protobuf::libprotobuf nor gRPC::grpc++, so
the generated proto sources rely on default system include paths. That
works on Linux (/usr/include) but not on macOS, where Homebrew installs
under /opt/homebrew. Add the Homebrew prefix to include/link dirs on
Darwin, mirroring the llama-cpp backend that already builds on Darwin CI.

* fix(ds4): install nlohmann-json on Darwin CI for ds4 backend

After the protobuf include-path fix the ds4 darwin build advances to
compiling dsml_renderer.cpp, which includes <nlohmann/json.hpp> and
#errors when absent. On Linux the header comes from apt nlohmann-json3-dev
in the build image; the macOS runner had no equivalent. Add the
header-only nlohmann-json formula to the shared Darwin backend brew
install/link list and Homebrew cache, alongside the existing deps.

* fix(ds4): build proper OCI image tar for Darwin backend

The darwin packaging referenced scripts/build/oci-pack.sh, which was
never added to the tree, so it fell back to a plain 'tar' that omits
manifest.json. 'local-ai backends install' then rejects the tarball
with 'file manifest.json not found in tar'.

Use './local-ai util create-oci-image' (already built by the 'build'
prerequisite of the backends/ds4-darwin target), mirroring
llama-cpp-darwin.sh, to emit a real OCI image the installer accepts.
