output ToolMessage content blocks from generate_streaming_response()

[yangm2]

The ToolMessage blocks are logged but not returned in the output stream ...

tenantfirstaid/backend/tenantfirstaid/langchain_chat_manager.py

Lines 207 to 216 in df26b7d

	# Messages sent back by a tool
	case ToolMessage():
	for b in m.content_blocks:
	match b["type"]:
	case "text":
	self.logger.info(b["text"])
	case "invalid_tool_call":
	self.logger.error(b)
	case _:
	self.logger.debug(f"ToolMessage: {m}")

We don't want to send these to the frontend but generate_streaming_response() is also used in the LangSmith evaluation runs it would be useful to get the tool call and the tool response in the experiment outputs to get a better picture to debug where a problem might be.

Either generate_streaming_response() needs to return more blocks or run_langsmith_evalutions.py needs to call a different (helper) function.
