Find Boolean-conditional smells

Recipe IDorg.openrewrite.kotlin.bestpractices.FindBooleanConditionalSmells$KtRecipeArtifactio.moderne.recipe:recipes-kotlin

if (x) true else false, its inverse, !x.isEmpty() / !x.isBlank() family negations, if (x == null) null else x.foo(), if (x != null) x.foo() patterns, and if (return …) else … early-return ladders — each is the long form of a single Kotlin operator or method.
