Fixes (#22280)

* fix ollama chat tool calling

handle dict arguments, streaming fallback, and message format

* pin setuptools<81 to ensure pkg_resources remains available

When ensure_torch_dependencies() installs torch/torchvision via pip, it can upgrade setuptools to >=81.0.0, which removed the pkg_resources module. rknn-toolkit2 depends on pkg_resources internally, so subsequent RKNN conversion fails with No module named 'pkg_resources'.
