Sonnet 3.5 and Haiku 3.5 do not support thinking and hence should not auto enable the thinking tag. This PR fixes that.

Let's add claude 3 to exclusion.
It might make more sense to change it to if model.includes("claude") && ... instead of checking underlying provider name, since the same issue will happen for other providers like bedrock etc

@uinstinct claude 4 models can contain "3" in their model string because they can include a date like claude-sonnet-4-11032025
