Conflicts:
- `app/models/status.rb`:
Minor upstream refactor moved hook definitions around,
and glitch-soc has an extra `before_create`.
Moved the `before_create` accordingly.
- `app/services/batched_remove_status_service.rb`:
Minor upstream refactor changed a block in which glitch-soc
had one extra call to handle direct timelines.
Adapted changes to keep glitch-soc's extra call.
* Prepare Mastodon for zeitwerk autoloader (Rails 6)
Add inflections and rename/move a few classes.
In particular, app/lib/exceptions.rb and app/lib/sanitize_config.rb
were manually loaded while still in autoload paths.
* Add inflection for Url → URL
