Find Kotlin logging smells
Recipe ID
org.openrewrite.kotlin.logging.Logging$KtRecipeArtifactio.moderne.recipe:recipes-kotlinSearch-only recipes for SLF4J, kotlin-logging, java.util.logging, log4j 1.x, and println/printStackTrace usage. Covers eager-message construction (string templates and concatenation), redundant level-check guards, LoggerFactory.getLogger shapes that could be KotlinLogging.logger { }, unstructured-output calls that bypass the logger, and logger-declaration smells (naming, visibility, instance-field placement).
