  *
- * For ZAI GLM-4.x models, we auto-enable thinking via the Z.AI Cloud API format:
- *   thinking: { type: "enabled", clear_thinking: boolean }
- *
- * - GLM-4.7: Preserved thinking (clear_thinking: false) - reasoning kept across turns
- * - GLM-4.5/4.6: Interleaved thinking (clear_thinking: true) - reasoning cleared each turn
- *
- * Users can override via config:
- *   agents.defaults.models["zai/glm-4.7"].params.thinking = { type: "disabled" }
- *
- * Or disable via runtime flag: --thinking off
- *
- * @see https://docs.z.ai/guides/capabilities/thinking-mode
  * @internal Exported for testing only
