Research direction
Start by reading the repository's existing Scalafix rules and their tests to find the pattern for rewriting implicit requirements and adding imports. Implement the transformation for code requiring cats.effect.Spawn[F] alongside cats.Parallel[F], including descendants, and verify that the result only requires Spawn[F] with the specified import.
