zoutao 0952ce3410 fix(apicompat): include streamed arguments in function_call_arguments.done
Gemini/Antigravity delivers tool arguments as one complete object, so this
converter synthesizes the Responses tool-call stream itself and therefore owns
its self-consistency. The done event was built without Arguments, leaving it ""
while the preceding delta carried the entire JSON. Clients that reconcile the
done payload against the accumulated deltas (OpenAI Responses SDK); Qoder's
reconcileToolCall) reject that mismatch as inconsistent_tool_call and abort the
turn non-retryably, so every tool call through the gateway failed.

Emit state.CurrentArgs, which closeCurrentResponsesItem already uses for the
item, restoring sum(deltas) == done.arguments == item.arguments.

Regression test asserts the delta sum equals the done payload and fails closed
when Arguments is dropped.
