* Fix TestEngine compatibility with Kotlin 2.3.x

In Kotlin 2.3.x, the Kotlin Gradle Plugin adds dependency constraints
to the runtimeClasspath configuration and marks it as non-declarable
(canBeDeclared=false). When TestEngine.copyRecursive() copies such a
configuration, Gradle throws:

  GradleException: Dependency constraints can not be declared against
  the runtimeClasspath configuration.

Fix by moving copyRecursive() inside the try block and catching
GradleException (which is the parent of ResolveException, so both
are handled). On failure the code falls back to using direct
dependencies only, as before.
