bug: Correct categorization and detection for heavier tests

[planetf1]

#372 and #326 optimized tests to run cleanly, to the best of the machine's capability, on a macbook m1 32GB

However there remain other tests which are not running cleanly in a better resourced environment (for example >64GB ram/gpu)

Example from hugging face tests:

The whole set will fail if ollama is not running (despite selecting not to run ollama tests:

Some fail with GPU memory issues (more management is needed):

E       torch.OutOfMemoryError: CUDA out of memory. Tried to allocate 256.00 MiB. GPU 0 has a total capacity of 79.19 GiB of which 9.06 MiB is free. Including non-PyTorch memory, this process has 79.16 GiB memory in use. Of the allocated memory 78.05 GiB is allocated by PyTorch, with 2.00 MiB allocated in private pools (e.g., CUDA Graphs), and 112.10 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation.  See documentation for Memory Management  (https://pytorch.org/docs/stable/notes/cuda.html#environment-variables)
