Add the required PR labels before merge.

As of August 25, 2026, the PR page lists CMake, CUDA/C++, and Cython / Python, but not improvement or non-breaking. (github.com) Add both labels because CI requires them for this PR.

As per coding guidelines, each PR must be labeled according to whether it is a "breaking" or "non-breaking" change (using Github labels).
