Claude: This PR was written by Claude Code on behalf of @apiology.

Problem

Methods from a Rails engine's app/ directory are not found:

class Post < ApplicationRecord
  include Turbo::Broadcastable # turbo-rails: app/models/concerns/turbo/broadcastable.rb
end

# Post#broadcast_replace: no definition
Post.new.broadcast_replace

This affects every engine that keeps code under app/, including turbo-rails, activestorage, actionmailbox, solid_queue and devise.

Solution

Collection::Gem#without_yard now parses app/**/*.rb alongside the gem's require paths, matching the {lib,app}/**/*.rb files YARD read before castwide#1378, without the plugin hook of castwide#1404 and castwide#1407.

YARD's ext/ glob is not included.

Claude: Closing in favor of the convention-hook approach: castwide#1404, castwide#1407 and iftheshoefritz/solargraph-rails#228.
