Research direction

Start by reading the Scala 3 LTS PR #637 and Scala 3 PR #24109 linked in the issue to understand the required JDK and compiler-option changes. Inspect the cats build configuration and compatibility checks, then verify that JDK 8 is no longer supported and that -Yfuture-lazy-vals is enabled without sun.misc.Unsafe usage.
