"""Native tool-call results must be threaded by CONVERTED-call position.

When an OpenAI/Anthropic model emits several tool_calls in one round and one
fails to convert (hallucinated name or bad-JSON args), it is dropped from
tool_blocks (so it produces no result) but used to stay in native_tool_calls.
_append_tool_results indexed tool_result_texts by native-call position, so the
surviving result was attached to the wrong tool_call_id and the real call was
answered with an empty string. _resolve_tool_blocks now returns the converted
calls aligned 1:1 with tool_blocks/tool_result_texts, and that aligned list is
what is threaded back.
