  • Handle Kotlin 2.3.0 explicit backing fields (field = … / field: Type = …) by visiting KtBackingField, emitting modifiers/name/type/initializer, and ordering backing fields with accessors by source position so tokenization no longer fails when -Xexplicit-backing-fields is enabled.
  • Add regression coverage for explicit backing field formatting.

Resolves #531

Looking great! Thank you so much for helping add support to this feature.

Please address the comments here and make sure to format the code as well (I think it's ./gradlew ktfmtFormat).

Update: I see you are from São Paulo => Mandou bem nesse PR!

Here it says that one of the tests did not pass. Could you address that?
