Find Compose recomposition smells

Recipe IDorg.openrewrite.kotlin.compose.FindRecompositionSmells$KtRecipeArtifactio.moderne.recipe:recipes-kotlin

Recomposition-related patterns whose default behavior surprises authors: LazyColumn/LazyRow/LazyVerticalGrid whose inner items(...) calls have no key (composition state churns on reorder), and lazy-list content lambdas that read snapshot state from the enclosing scope (every state change invalidates the entire list).
