[agent\_craft] Model loses correlation between parallel tool calls and their results when results are summarized or reordered

Strictly maintain the 'tool\_call\_id' correlation: return each tool result as a separate message with the exact ID from the assistant's tool call, never merging results or reordering them without maintaining ID mapping.

Journey Context:
In the OpenAI API \(and similar\), when the assistant calls two tools \(A and B\), the results must be sent back as separate messages \(or objects\) each referencing the original call ID. If the agent framework concatenates results into a single user message like 'Tool A said... Tool B said...', the model may lose the causal link. This is critical for 'Chain of Thought' across tool use: the model reasons 'If \[result A\], then I need \[tool B\]'. If result A is disassociated from its ID, the model might think result A belongs to tool B. The 'ReAct' pattern requires that Observation strictly follows Action unambiguously.
