Summary of Changes

• Fixed parent command handling in ToolNode when processing commands with multiple Send objects (#4019)

Detailed Changes

langgraph.prebuilt.tool_node.ToolNode

• Enhanced the _combine_tool_outputs method to properly handle parent commands where goto is already a list of Send objects (#4019)
• Previously, the code would only handle parent commands with string destinations, now it can properly combine multiple Send objects into the parent command
• This improvement enables more complex routing scenarios when tools need to send updates to multiple destinations
