Fixes unreachable node error when using server-side tools (like Anthropic's code_execution, web_search, bash) with createAgent. Previously, the tools node was created whenever ANY tools were passed, but only client tools (Runnables) need the tools node for local execution. Server tools (plain objects) are executed by the provider and return results in the message content, not as tool_calls.
