Check for misnamed specs

Check the specs directory (except spec/support/\* and spec_helper.rb) for new files that don't end in _spec.rb

Start by inspecting the repository's existing spec-checking or bot entry points, then review files under spec/. Exclude spec/support/* and spec_helper.rb, and identify new files whose names do not end in _spec.rb. Done means the check reliably reports those misnamed spec files without flagging the exclusions.
