Find `java.io.File(...)` allocations inside a `@Composable` body

Recipe IDorg.openrewrite.kotlin.compose.FindSideEffectAllocationsInBody$KtRecipe

Artifactio.moderne.recipe:recipes-kotlin

Filesystem objects allocated inside a @Composable body get rebuilt on every recomposition. Even if the constructor is cheap, the I/O performed by callers (File.exists(), File.length()) often is not. Move the allocation into a remember { File(...) } block or out of the composable entirely.
