 * number, array, or `null`).
 *
 * @remarks
 * Non-fatal. The adapter does NOT throw this — it instantiates it inside
 * `executeAndPersistToolCall`, pulls `.message` into a {@link @nhtio/adk!Tokenizable}, and persists a
 * `ToolCall` record with `isError: true`. The model sees the formatted message in the next
 * iteration's history and can self-correct. Consumers introspecting persisted error results
 * can match on the `E_WEBLLM_CHAT_COMPLETIONS_INVALID_TOOL_CALL_ARGS` code substring.
 *
 * Printf args: `[reasonHeadline, rawArgs]`.
 *   - `reasonHeadline` — short reason such as `'are not valid JSON'` or
 *     `'must be a JSON object; received array'`.
 *   - `rawArgs` — the raw `arguments` string the model emitted, echoed back verbatim so
 *     the model can see what it sent.
