ci: Fix CodeQL build failure caused by ASan conflict

Debug build enables ASan (-fsanitize=address), which crashes when
protoc runs during protobuf code generation — ASan runtime conflicts
with CodeQL's own instrumentation. Switch to Release since CodeQL
does its own analysis and doesn't need sanitizers.
