/**
* The default-order resolution, client-side (chunk 2): the UI populates a
* fresh model pick's thinking level with the SAME level the engine build
* runs for an unset record — first DEFAULT_THINKING_ORDER entry the model
* supports (Platform's interlude bd68486 moved the ordering into the core
* barrel exactly for this). These tests pin the helper against the
* server's defaultThinkingLevel semantics (src/agent/models.ts).
