Find Compose effect handler issues

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

Artifactio.moderne.recipe:recipes-kotlin

Effect handlers misused: LaunchedEffect(Unit)/LaunchedEffect(true) placeholder keys, DisposableEffect lambdas missing onDispose { }, rememberCoroutineScope() mis-placed inside a lambda, LaunchedEffect inside loops, and side-effecting calls (logging, File) inside the composable body rather than an effect block.
