c58e711a - Fix TypeError in convert_rope_params_to_dict when ignore_keys is a list (#44272)

Fix TypeError in convert_rope_params_to_dict when ignore_keys is a list (#44272) Fix TypeError when ignore_keys_at_rope_validation is a list In `convert_rope_params_to_dict`, the `ignore_keys_at_rope_validation` parameter is expected to be a set but can arrive as a list when model configs are deserialized from JSON (e.g. Qwen3.5 via vLLM). The union operator `list | set` raises TypeError on Python 3.12+. Wrap the value in `set()` to normalize all iterables before the union. `set(already_a_set)` is a no-op copy, so existing behavior is preserved.
