The implement is LGTM. Could you please add a test for the modelSelectList selector to cover openrouter env logic?

The implement is LGTM. Could you please add a test for the modelSelectList selector to cover openrouter env logic?

@arvinxx I checked the test cases and I found that the core logic has already been covered by existing test cases. Openrouter reuses the customModelName property to introduce custom models in env and reuses parseModelString to parse it, and this flow has been well covered already. There was nothing special about Openrouter. Can yoy be more specific on the additional test coverage you have in mind?

@danielglh I mean if there is an openrouter?.customModelName field, and the result should be snapshot.
