Find `runCatching { }` blocks that may swallow `CancellationException`

Recipe IDorg.openrewrite.kotlin.functional.FindRunCatchingSwallowingCancellation$KtRecipe

Artifactio.moderne.recipe:recipes-kotlin

runCatching { } catches every Throwable, including kotlinx.coroutines.CancellationException. Inside a coroutine that's a bug — CancellationException is the cooperative-cancellation signal, and swallowing it stops the coroutine from cancelling. Either avoid runCatching in suspending code, or rethrow with .onFailure { if (it is CancellationException) throw it } before any other handling.
