fix(ci): collapse setup.py formatting for current ruff; pure-python protobuf for train

CI's ruff (latest) collapses the short find_namespace_packages call
that older local ruff accepted multi-line. train (3.9) hit the
tensorboard-vs-protobuf>=4 'Descriptors cannot be created directly'
clash — PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python on the train
job avoids it without pinning protobuf in packaging.
