Hi all, I noticed the recently added gpt-5.4 models have missing capability that enforces structured json response, unlike gpt-5/5.2, gpt-5.4 seems to be missing:
```LLMCapability.Schema.JSON.Basic,
LLMCapability.Schema.JSON.Standard,```
Is this intented? What is the suggested way to enforce structure json response when using koog with gpt-5.4?

This looks like a bug, since these models should support native structured output. Feel free to create an issue
