Enhancement Notes

• We’ve relaxed the requirements for the ToolCallDelta dataclass (introduced in Haystack 2.15). Previously, creating a ToolCallDelta instance required either the parameters argument or the name to be set. This constraint has now been removed to align more closely with OpenAI's SDK behavior.
  The change was necessary as the stricter requirement was causing errors in certain hosted versions of open-source models that adhere to the OpenAI SDK specification.

Bug Fixes

• Fixed a bug in the print_streaming_chunk utility function that prevented ToolCall name from being printed.
