Describe the bug

Extension methods from companion object are suggested only after (some) Object methods, Product methods and even orphan extensions like ensuring.

Foo.scala

case class Foo()

object Foo:
  extension (f: Foo)
    def qux: Unit = ()

test.scala

val _ = Foo().@@

Seems like of the Object methods, only the ones that are overridden by compiler-generated methods of a case class rank higher, but that's still unwanted.

Expected behavior

I'd expect extension methods from the companion object to be suggested before orphan extension methods.
It'd be useful to also de-prioritize methods inherited from Object and Product.
