flags Class#descendants / Class#subclasses on constant (or self) receivers. skips non-constant receivers so tree-model #descendants don't false-positive.
register in default.yml + default_cops.yml as pending, require it from the top-level entry point.
include a 'good' example showing an explicit registry, plus pointers to eager loading and ActiveSupport::DescendantsTracker for cases where reflection is unavoidable.

as requested this is the PR including the 👮♂️ cop.
It supersedes #356.
PS: I'm looking for a new adventure in case anybody is looking to hire someone or in case someone would like to work with a (Ruby/Rails/Crystal) dev and I'm also open to move to a PO/PM role.
PPS: If we ever ever meet, feel free to ask me about the Ruby conference guestbook
