agent: infrastructure

When does this happen?

IF Upgrading transformers to version 4.50.0 raises RuntimeError: register_pytree_node() got an unexpected keyword argument 'flatten_with_keys_fn'.

How others solved it

THEN Pin transformers to version 4.49.0, which does not exhibit this error. Alternatively, wait for a bugfix release or adjust the underlying dependency (e.g., torch) to match the required API. Monitor the transformers repository for a fix.
