Find Compose recomposition smells
Recipe ID
org.openrewrite.kotlin.compose.FindRecompositionSmells$KtRecipeArtifact
io.moderne.recipe:recipes-kotlinRecomposition-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).
