-Wmissing-braces warns in nvtx3.hpp

[bdice]

I am compiling nvtx3.hpp with -Wmissing-braces and I get warnings in these locations:

/home/coder/rmm/build/conda/cuda-12.8/release/_deps/nvtx3-src/c/include/nvtx3/nvtx3.hpp:1930:9: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
 1930 |         0,                              // payload value (union)
      |         ^
      |         {}
/home/coder/rmm/build/conda/cuda-12.8/release/_deps/nvtx3-src/c/include/nvtx3/nvtx3.hpp:1932:9: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
 1932 |         0                               // message value (union)
      |         ^
      |         {}

I'm getting this when compiling for IWYU, which uses clang under the hood.
