Support parallel tool calls by executing each tool sequentially.
It determines the current tool call by checking how many tool calls have corresponding
ToolMessagesalready in the message stack.This requires no new state fields or nodes, making the logic more graph-agnostic.
Sections that assumed the
AIMessagewill be last in the stack were changed to now find the lastAIMessage, skipping over anyToolMessage.True Parallel execution was NOT implemented due to maintainability and extensibility concerns.
