Added dedicated `finish_reason` field to `StreamingChunk` class to improve type safety and enable sophisticated streaming UI logic. The field uses a `FinishReason` type alias with standard values: "stop", "length", "tool_calls", "content_filter", plus Haystack-specific value "tool_call_results" (used by ToolInvoker to indicate tool execution completion).

Updated `ToolInvoker` component to use the new `finish_reason` field when streaming tool results. The component now sets `finish_reason="tool_call_results"` in the final streaming chunk to indicate that tool execution has completed, while maintaining backward compatibility by also setting the value in `meta["finish_reason"]`.
