Overview

The mountable engine: wires autoloading, migrations, locales, the ActiveRecord macros, importmap pins, asset paths, and boot-time model configuration into the host app.

LIB_ROOT =

Zeitwerk: the gem keeps its ActiveRecord models under lib/chats/models (same layout as the moderate gem) so the whole domain ships in lib/ and the engine’s app/ tree only holds the web layer (controllers, helpers, views). For that to autoload correctly we manage the loader by hand:

- `push_dir(lib/chats, namespace: Chats)` makes lib/chats/models/...
  autoloadable *under the Chats namespace*.
- `collapse(models)` + `collapse(models/concerns)` mean the files in
  those folders define Chats::Conversation / Chats::Messager — not
  Chats::Models::Conversation.
- The SPINE files (version/errors/configuration/macros/engine) are
  required explicitly by lib/chats.rb at boot, so they must be
  *ignored* by the loader or Zeitwerk would complain about double
  definitions / unmanaged constants.
