//   - thinking_budget (number) → mapBudgetToEffort() → --effort {low,medium,high,xhigh,max}
//     (de CLI heeft geen --thinking-budget flag — alleen --effort)
//   - max_turns blijft audit-only: de CLI heeft géén --max-turns flag.
//     De waarde wordt gesnapshot voor cost-attribution maar niet doorgegeven.
//   - allowed_tools → --allowedTools (komma-gescheiden lijst)
